Lauren Conrad was accompanied by a male friend as she stepped out of Katsuya in LA yesterday following dinner with pals. It was LC's latest evening out after also recently partying at Beacher's Madhouse, where she reportedly ran into her ex, Derek Hough.The couple split in November and LC's been busy with family, fashion, and philanthropy since. Over the holidays, she treated teens from the LA Children's Hospital to a shopping spree at Kohl's before heading out of town for the break. LC was back in the spotlight for New Year's Eve, which she celebrated in Las Vegas with Stephanie Pratt.

Spotted: Kristin Cavallari catching a quick bite at Katsuya after her secoond performance on Dancing with the Stars, Monday September 26.
In other related DWTS news, MTV News caught up with Cavallari and her partner, Mark Ballas, who sized up their competition. They both said everyone brought their own talents to the table and they are on the lookout for them all.
"No one's bad!" Cavallari said. "That's the thing. I think it's going to be a tough season."

Spotted: Audrina Patridge and boyfriend Corey Bohan leaving Katsuya on Sunday night. Corey tweeted: "After my crash at @xgames yesterday I had xrays on my wrist. The good news is it's not broken. 2nd xray will be in a week to double check"
In other news, Audrina recently told More! Magazine, “I haven’t had facial surgery or anything like that, but if I felt I needed it, I would.”
But while she refuses to rule out cosmetic surgery, she does advise her young fans to wait before undergoing such drastic procedures.
“Young girls should enhance what they already have, and if they feel they want surgery they should wait ten years, or they might regret it,” she added.
And while we reckon the brunette beauty looks great exactly how she is, there is one area of her perfect beach bod that makes her feel insecure.
“I actually have a chest problem,” she said. “It’s genetic and I try not to let it get to me, but it can look bad in a bathing suit. It looks like it’s higher on the right than on the left.”
But rather than let her insecurities get the better of her, the 26-year-old insists she does her best to ignore any negative comments.
“I learnt the hard way, as it makes you so bummed out. For my own sanity I don’t live off people’s opinions of me.”
And unlike most women, the lucky lady doesn’t have to worry about following a strict diet to keep her fine figure in tip-top shape.
“I actually have a problem putting on weight. I’ve always been skinny,” she explained. “But I do something active every day. I got to the beach, run, do Pilates or play volleyball.”

Kristin Cavallari and her boyfriend Jay Cutler were spotted at Katsuya Friday night. Jay, who's the Bears quarterback, isn't exactly a fan favorite in Chicago these days so we're guessing he'll be laying low withKCav in LA for a while.
Jay came under some pretty tough scrutiny when he left the Bears game last weekend because of a knee injury, which many fans didn't believe was severe enough to remove him from the game. His removal from the game, some think, cost the Bears a trip to the Super Bowl. Ouch.
Jay seems to be doing well, though, and his personal life isn't suffering. Kristin recently gushed that she's "in love" with her football beau. They've been dating for a few months now and are still going strong.

Partaking in a night out on the town, Kristin Cavallari was spotted enjoying the west coast nightlife in Hollywood, CA on Friday (November 12).
Joined by a few friends, the former "Hills" star headed to Katsuya restaurant as she tweeted before the outing, "Ok I'm getting off my a**. Bring on the lycee martini"
