(Gregg DeGuire/WireImage)The beginning of another awards season in Hollywood means that it's time for Stacy Keibler — the wrestler and dancer-turned-actress and main squeeze of A-lister George Clooney — to get ready for her close-up. Keibler, who turned 33 on October 14, says that the most important thing she does on the days she faces countless camera flashes is hydrate. "Usually, the day of a red carpet, I juice in the morning and I drink tons of water. I [also] usually work out," Keibler reveals to omg!. Actually, Keibler's pre-red carpet routine isn't much different than what she does on a daily basis to keep her fab figure. "Right now I'm doing a cleanse - it's from the book 'Clean' by Dr. [Alejandro] Junger - because I think you can really kill yourself with food," she says. "I just make sure to eat as organically as possible, lots of fruits and vegetables."

Kate Moss (Mert Alas & Marcu Piggot/Vanity Fair)When Kate Moss landed the Calvin Klein ad campaign with Mark Wahlberg, it helped propel the then-teen to superstardom in the modeling world. The black-and-white photos, snapped in 1992, featured the two stars pressed up against one another with Wahlberg's muscular arms (and abs!) a stark contrast to Moss' frail frame. While the images have become an iconic representation of the era, and launched the "heroin chic" look of skinny models with dark circles under their eyes, Moss has regrets about participating in the shoot, saying it caused her emotional issues.

Adam Levine may have recently made his first public appearance with his new girlfriend (yet another Victoria's Secret model, Behati Prinsloo), but he's still forging ahead with plans to buy a new bachelor pad. The Maroon 5 rocker has purchased a 6-bedroom, 7-bathroom house in the Benedict Canyon area of Beverly Hills, which means he will officially have the fabled 90210 zip code as his address.

(Ben Watts/Lucky)Oops … she did it again! Britney Spears has found herself smack dab in the middle of another controversy pertaining to her photo spread in the December issue of Lucky, which hit the web on Friday.

"The X Factor" judge dons several different relatively conservative outfits in the mag and reveals some of her fashion secrets — for example, she hates socks. While the whole thing seems pretty innocuous, there's been a big backlash from her fans, who are complaining that the entertainer seems to be wearing a bad wig in pictures that appear to be heavily retouched.

While we're sure she can't wait to marry fiancé Justin Theroux, we are actually talking about her love of plunging necklines. On Saturday, Aniston turned heads on the red carpet at the LACMA 2012 Art + Film Gala Honoring Ed Ruscha and Stanley Kubrick wearing a black silk Tom Ford gown that showed some serious skin. Her chest area was on display down to her stomach, and she looked as confident as ever rocking the look. Perhaps part of the confidence came from a sheer panel that ran from her neckline down, preventing any embarrassing wardrobe malfunctions. And, yes, she accessorized with her huge rock — the blinding diamond engagement ring Theroux gave her over the summer.

Britney Spears (Ben Watts/Lucky)We'll admit that part of the reason we tune in to "The X Factor" is to see what Britney Spears is wearing. Through the years she's been known to get people buzzing over some of her fashion choices (the barefoot bathroom pit stops come to mind), but now seated alongside Simon Cowell at the judges table, it's like our little Brit-Brit is a whole new stylish woman. This extends to her new cover shoot in Lucky, in which she also talks fashion from a down-home perspective — from how she lives in sweatpants when she's hidden away at home to the one article of clothing that she absolutely, positively refuses to wear.

The rivalry from their "Laguna Beach" days is still going! The year after Lauren Conrad donned a sweet Minnie Mouse costume to a Halloween bash, her one-time classmate and the woman who took over as the star of "The Hills" when she left, Kristin Cavallari, stole the look for herself. The feud between Cavallari and Conrad stems way back to when both ladies were after that stud Stephen Colletti, who more recently was a regular on the CW's "One Tree Hill." Cavallari came out the winner back then when it came to the man they both wanted, but will she win when it comes to costumes? It's up to us to decide ... who wore it best?!
