Even celebrities have celebrity crushes: “I think I’m in love with @MsLeaMichele! So beautiful and so talented!” Kim Kardashian tweeted of the 23-year-old Glee starlet. Kim tweeted a picture of her and Michele getting cozy after the Golden Globes on Sunday night. Kim is hard at work tuning up her own vocal chords for her new single, “Turn It Up,” which may explain why she’s crushing on Glee’s gifted Ms. Michele. Backstage at the Late Show with David Letterman on Wednesday night, guest star Olivia Munn munched on some snacks, being careful not to spill any crumbs on her décolletage. staff caught the cookie monster mid-bite, tweeting, “Olivia Munn enjoys her complimentary dressing room cookies.” Munn confessed to Letterman that she was a nerdy child, but smoothly transitioned to the cool crowd when she moved from Japan to Oklahoma and started throwing high-school parties. On Thursday night, Munn appeared in the first episode of NBC’s new comedy Perfect Couples. Munn clearly enjoyed chatting with Dave on the Late Show, so much that she wanted a souvenir of the experience. “I asked for the cue cards from @Late_Show… Now they’re on my hotel bed. Yay City!” said the Daily Show correspondent tweeted. Munn took a break from filming her new movie I Don’t Know How She Does It to tape the show. Does Ricky Gervais have his sights set on an Oscar? The Golden Globes host dressed the part at least, posing for a Twitter picture for Ellen DeGeneres this week. "Please enjoy this photo of Ricky Gervais in my underwear,” she tweeted. And the picture may have come in handy for a few stars on Sunday night: He may have been mean on the outside, but deep down, Ricky Gervais is just a hairy Brit in gold lamé panties. Justin Bieber made his acting debut on CSI in September, and according to recent Twitter updates, America’s latest heartthrob will reprise his roll as troubled teen Justin McCann in coming episodes. Bruised, battered, and addicted to licorice twists, Bieber tweeted from the set: “Unsub on the loose… they call him the #redvinereaper.” Those of you with Bieber Fever, tune in to CBS on February 17 for his return to the crime drama. Apparently this Golden Globe nominee was having some, er, issues in the dressing room prior to the show: “Nothing fits meeee!!!! I’m not going to the Golden Globes!!!!!!!!” tweeted Sofia Vergara, who plays the impossibly sexy, hilarious young wife of an older man on ABC’s Modern Family. Not surprisingly, the Colombian beauty looked nothing short of stunning on the red carpet. Entourage star Jeremy Piven has been known to show off his skills on the basketball court as well as the big screen. It’s no surprise he’s a big fan of the sport, and was all smiles next to Chris Paul of the New Orleans Hornets in a recent picture. Piven was beaming after the Hornets defeated Orlando last week, tweeting, “With Chris Paul after the win tonight over the Magic!” Ben Stiller captured co-star Casey Affleck looking a little weary on the set of their upcoming movie, Tower Heist. Perhaps he’s recovering from a Nathan’s hot dog-induced food coma? The action comedy also stars Matthew Broderick, Eddie Murphy, Tea Leoni, and Gabourey Sidibe as a group of Wall Streeters who find themselves involved in a Bernie Madoff-type, Ponzi scheme scandal. On USA’s long-running crime series SVU, Detectives Olivia Benson and ‘Fin’ Tutuola have gone after their fair share of sex offenders—and sometimes catch them at the end of the show. But in real life, Mariska Hargitay and Ice-T’s team efforts invariably pay off. “The homegirl Mariska at the wrap party! Gotta love her... We've made alota money together the past 10 years!!” tweeted Ice-T. Jimmy Fallon certainly had his hands full with some good-looking people at the Golden Globes. After presenting with January Jones, Fallon tweeted this photo of Zac Efron and Eva Longoria. “Our table had fun at the globes,” he tweeted, with the hashtag #table101. He got plenty of jealous Twitter followers. Their characters might not be friends on Glee, but Dianna Agron tweeted her excitement about her co-star’s Golden Globe victory Sunday night. Colfer took home the Best Supporting Actor trophy for his portrayal of the gay character Kurt Hummel, and Argon snapped a photo of him hugging his statue. It was a big night for Glee overall: The musical comedy took home the Golden Globe for Best Musical or Comedy show and Jane Lynch won for Best Supporting Actress. Eva Longoria wasn’t going to let not being nominated for a Golden Globe keep her away from the action! Despite reports that Desperate Housewives star was “at the end of her rope” before the awards show, she tweeted photos getting her hair and makeup done. From her Twitter updates, it looked like she had fun throughout the night: Not only did she pose by the Golden Globe by the entrance, Longoria also sat next to Zac Efron at what had to be one of the most fun tables at the show. After the big Golden Globe win for Best Musical or Comedy Series, Cory Monteith got back to work on the set and posed in his character’s football uniform. At least, we think he went back to work: Monteith told his followers he would give them a prize if they correctly guessed what he was up to in the photo. Any guesses?
