Spencer Pratt isn't the only one in his family experiencing some breakup drama.
His sister Stephanie Pratt and her motocross beau Josh Hansen "went their separate ways," her rep confirms to PEOPLE.
There are no further details about the split, but it seems that the relationship did not end on amicable terms.
"Another dysfunctional move by Stephanie pratt," Hansen Tweeted Monday. "I was under the impression u had to be someones bf in order to get dumped."
In response to Hansen's Tweet, Stephanie Tweeted, "No josh Hansen u were dumped stop acting like a child. Keep star [expletive] ur (sic) way into Hollywood. Now pls GO AWAY!!!!!!"
A rep for Hansen says the two were never an official item and that the racer is "moving on." Meanwhile, Hansen has kept himself busy by Tweeting to former Girls Next Door star Holly Madison.

What a jerk he turned out to be! And if, as he says he was never her boyfriend why did he DM so many of her fans talking about how much he loved her? Liar Liar pants on fire!
Steph can do so much better than this little boy...

We spotted "The Hills" beauty and her boyfriend Josh Hansen leaving Katsuya on Tuesday after dining together at the Hollywood hotspot. The couple dispelled rumors of a split by holding hands. Stephanie looked great in a short gray jumpsuit and wedge heels.

Hey guys, sorry it took me a couple weeks to write my last blog on hills. I'm sure most of you saw the finale. We didn't get to watch it beforehand, we all watched it together at the live after show. It still hasn't really hit me that it's really over. I thought I'd get real emotional at the finale, but instead I look at it like it's graduating and moving on in life. I'm excited for the unknown and what the future beholds!! Alrighty sooooo I have to say that I thought the end was very clever! Because it's poking fun at how everyone asks if the hills is fake. The little montage at the end of each of us were pretty cool. It shows how everyone has changed and matured. It's crazy to think that 6 years ago the hills was similar yet so different! I was the only original cast member on the hills for the entire series!!! At least Whit and Lauren were at the after show for a little reunion with us. And it was also a mini laguna beach reunion with Lo, Lauren and Kristin.
The final season of the hills ended with people moving, getting boyfriends, getting engaged, everyone maturing and choosing their next path in life. It's been a long 6 years filled with lots of change - experiencing LA life on national tv! One day I'll show my kids the DVDs but not until they are older! haha
Now I keep getting a bunch of questions regarding me living on the beach in Hermosa and also if I met Corey through Stephanie and Josh (lol) and also what I'm doing after the hills..... Well here it goes:
As far as me actually living in Hermosa... it was a gorgeous house, that hopefully one day I'll be able to afford!
Noo I did not meet Corey through Stephanie and Josh. I've known Corey for a very long time and for the hardcore fans out there you know he filmed with me during season 4. Josh actually knows Corey and my brother-in-law Kyle Loza. We have a lot of mutual friends, and no I did not set them up and I have not seen her since finale.
As far as what I'm doing after the hills..... I plan on continue going to auditions and yes my reality show with mark Burnett is still in talks. It would be about my life outside of The Hills bubble, and behind the scenes as far as balancing my Hollywood life with my family life and trying to pursue my dream, but also living life and dealing with realtionships, traveling, all along with the ups and downs. My family and a few real close friends would also be on it.
I hope that answers a lot of your questions! Feel free to ask me more, and I will try my best to answer them all! Either directly, through a blog like this, or in the Community!
xoxo

Don’t listen to reports that say Stephanie Pratt and her boyfriend Josh Hansen are broken up! The Hills star tells OK! exclusively they’re “completely untrue.”
Reports hit the web on Monday that Stephanie broke up with Josh right before he performs in the X Games this week.
But, Stephanie tells OK! exclusively, “This is completely untrue.”
Josh and I are happy,” she adds to OK!. “And I am proud to be supporting him this week at the X Games.”
Expect to see Stephanie at the X Games on Thursday supporting her man!

Stephanie couldn’t stop smiling when we asked about her new boyfriend, BMX pro Josh Hansen. She’s completely smitten!
It’s so nice to hear that things are going well for Stephanie Pratt. With The Hills ending, we’re glad to see that Stephanie, 24, has finally found one constant in her life … her new boyfriend, 26-year-old pro-racer Josh Hansen!
Since they met while filming the final season of The Hills, Josh has been Stephanie’s shoulder to lean on. “I think you just have to support each other no matter what,” Stephanie told HollywoodLife.com exclusively July 19 at the premiere of The Extra Man hosted by Vapiano in NYC. “I think what we say to each other every day is, ‘I’m really proud of you!’”
Josh knows exactly how to distract Stephanie from the harsh realities of life — he gets her to relax! “We like to watch Tropic Thunder,” Stephanie admitted. “It’s really funny. It’s an all star cast and it’s just hilarious!”
But it’s more than just a one-sided relationship. Stephanie is also completely supportive of Josh and his pro-racing career. “He has the X games next week,” Stephanie said. And she’s going to be his biggest cheerleader: “I definitely want to get some stickers for his helmet. That’s a must. Maybe I should get a shirt?”
“Once [the X Games] end, depending on how he does, we’re going to figure out how many days we have for a little vacation,” Stephanie said. “He wants to come to New York. He’s really bummed he’s not here right now. We might be back in August!”

If you're like 2.5 million other viewers, on Tuesday you tuned in to watch the final episode of the MTV series "The Hills." In that final episode, two-time defending X Games Super X champion Josh Hansen appeared due to his relationship with Stephanie Pratt, one of the stars of the wildly popular reality TV show. The two met after the final season of the show had started production, and their relationship became significant enough that Hansen figured prominently at the end.
Hansen's story is well known among supercross fans. The 26-year-old from Colorado was a rising star with several national amateur titles before going pro at 17. He accrued six regional supercross podiums between 2004 and 2005 before he lost his focus. Between a hard-partying lifestyle and a revolving door of sponsors, Hansen was on his way to being written off by the racing community as another story of lost potential.
But the past year has seen Hansen do more than just raise his profile through reality TV. He was tapped by one of the godfathers of the supercross industry, Pro Circuit's Mitch Payton, before last summer's X Games to ride a Pro Circuit Kawasaki -- a decision that paid dividends for both parties.
In April, Hansen returned to the supercross podium at Salt Lake City, winning the 250cc Lites and re-establishing himself as a threat well beyond the one-off arena of X Games. As he gears up for his shot at an X Games three-peat, it's tough not to root for Hansen. And now, thanks to "The Hills," that's exactly what millions of casual X Games fans who don't know a two-stroke from a four-stroke will be doing.
"A lot of people follow that show," he said when we asked him what it was like to be a part of "The Hills." "It's kind of crazy because I've never followed the show. I didn't know people were so pumped and hyped on it. However, I just want to be Josh the Dirt Bike Guy."
ESPN.com: Josh, how did you wind up meeting Stephanie Pratt and becoming a part of "The Hills" TV show?
Josh Hansen: Dingo [Luke "The Dingo" Trembath, star of the TV show "The Adventures of Danny & The Dingo"]. Dingo introduced me to her and got us set up right before the Vegas supercross. So I did my thing out in Vegas and came back and went on a date with her and then started hanging out with her.
Did you know who she was or anything?
Well, I kind of knew about "The Hills," like the show. Dingo explained it to me. But I didn't know her personally or anything, so it was just kind of like whatever. I just kind of went into it like, "Whatever happens, happens." She ended up being cool, and I've been hanging out with her and she's been fun. And then it just carried on and MTV got a hold of me. I wasn't really interested at first, but I did a few shows. At the ending of the show, Stephanie and I talked, and it was just a good closing to the show for her and her finding, I guess, love. It was a good ending for both of us.
I went over to Pro Circuit to see Mitch Payton at the time all of this started. He had just heard that you had been spending time in Hollywood and wasn't too into the concept of you being around that scene and hanging out with "Hollywood people."
Yeah, I think Mitch was pissed, but it wasn't like I was just up there partying every night and not doing [anything], you know? Yeah, I went up there and was doing the show and was hanging out with Stephanie, and then I would come back. I was riding and doing my stuff. After he saw that, he was fine. He just wanted to make sure I was on top of my stuff. That's what I was doing and that's what I'm doing now.
As far as the show, did they write you into it or just kind of drop in on what you and Stephanie were doing?
I don't know. ... They didn't really have to write in anything. It was all natural, you know? It was what we were working with and it just fit so good for the show. It made Stephanie happy, and I was good. I figured if it was time to go ahead and do the show, it was probably better to do it toward the ending -- like the last two final episodes -- because then it was done forever.
The show ran for six years, and you ended up being a big part of the final episode. Leading up to it, Mitch started following the show and knew the storylines and everything. I kind of sensed he was into the whole thing and you riding at the test track as the curtain came down on the show.
I think everybody just thought the worst about the whole thing right off the bat. Like, "Oh, Hansen is done racing" or "Hansen is already screwing up and going back to the old Hansen." It wasn't really like that. I think everybody was looking at it from the outside looking on in. I'm a racer, and I feel like I'm a good racer and I feel like I have the personality to do some stuff outside the sport. Nobody else really does it. I'm not going to just stick in my own little world of racing. It comes natural to me. This is what I do. This is how I want to be. People either support it or they don't. This is the way I want to live my life.
