I know being a reality TV star is tough, but Kristin Cavallari sure has an admirable work ethic!

We snapped the Hills honey on the beach yesterday, and her smile is totally contagious! After looking at these pics of her romping around on the sand, we're totally in a better mood - no photograph of LC would ever make us feel this way!

Nick and Vanessa's three-year relationship was on the outs for quite a while before they "officially" called it quits in June, but now they're "officially" back together!

After being spotted cuddling up in LA, Life & Style spied them out together at McFadden's Restaurant and Saloon in New York last Wednesday night.

"They seemed very laid back and were very friendly to the staff and fellow patrons," an eyewitness told the mag.

So it's on...for now. How long before it's off again?

Drew donned a pair of skates for a sexy photo shoot for Vs Magazine, where she and her film's co-stars, Ellen Page, Juliette Lewis and Lake Bell, recreated their roles as devilish derby dolls in Whip It.

Drew is making her directorial debut with the film, about a young Texan (Page) who rebels against her mother's wishes for her to join the pageant circuit, and instead joins a roller derby team.

Sounds like a rolling good time!

Ashlee, currently in the Big Apple doing promos for her new show, Melrose Place, was looking more Vampira than Violet last night!

With her auburn hair, pale skin, blood red lips and all black ensemble, looks like she's giving Queen Sophie-Anne (Evan Rachel Wood) a run for her money!

Think Ash would be more at home on the goth set of True Blood than one of LA's most infamous streets?

Another Olsen ex is being poached, this time by Rihanna!

Gatecrasher reports that the songstress was seen in LA with Mary-Kate's former fling, Travis London. The couple dined at Giorgio Baldi last weekend, and were spotted getting cozy at the Chateau Marmont on Monday.

I guess while Ri's ex Chris Brown is busy letting his mouth get him in trouble, Rihanna's letting a hot piece of arm candy do the talking for her!

Posh graces two different covers of Elle for October, and although she's revealing some sexy undergarments in one, the Spice Girl tells them that she's actually quite shy!

"I do have my insecurities. Maybe that is why I look a little bit serious. The kind of person who's going to stand on the red carpet and love the attention and have the big grin - I'm just not like that. I want to get in there, do what I've got to do, and get home to my kids," she tells the mag.

And although it's hard to think of such a public personality as someone who enjoys having a private life, Vic seems to have balanced both.

"David and I have a working relationship together, and we also have a private life together. Someone used the example recently of Brad and Angelina. They might be in a movie together, but that doesn't mean they're going to let someone film them at home," she said. "I don't do 'at homes' with my family. I don't march my kids down red carpets. It's just not how we choose to do things."

Is that a subtle dig at the famous families who do? Like, maybe good friends Tom & Katie?

Only Jake Gyllenhaal could make us this fond of facial hair!

Reese's main piece was spotted in a parking garage in Beverly Hills yesterday, and though the hunky actor remained expressionless as photogs snapped away, he still looked incredibly delish. We would suggest that he smile, but when you've got an equally sexy poker face, who cares!?

Thankfully this didn't involve smudged lipstick or a screaming catfight!

After getting her hair blown out, Lindsay Lohan had her designated driver/lover pick her up and whisk her away from the army of photographers camped outside the salon. Ahh, what else are girlfriends for?
