Halle Berry and Olivier Martinez looked like they were sharing a private joke leaving an LA art show yesterday. Olivier's been in town for the past week since Halle and Nahla welcomed him to the West Coast with a special happy birthday surprise. The pair stepped out for a lunch date before the Golden Globes Awards, though Halle decided to walk the red carpet solo in a short and sleek black gown. The best actress nominee didn't take home an award for her role in Frankie and Alice, but she was all smiles arriving at the star-studded afterparties. Her relationship with Olivier seems to going strong, as is her ex-husband's, Eric Benet, who recently announced his engagement to girlfriend of three years, Manuela Testolini.

Alexander Skarsgard slipped on a white oxford and exited his gym in West Hollywood yesterday. He's been spotted working out regularly to keep up that model Vampire physique. We saw the labor of his efforts last year when he spent a romantic weekend in Palm Springs hanging at the pool with Kate Bosworth and checking out dozens of live music acts during the Coachella music festival. This year's lineup includes Kanye West, The Kings of Leon, and Arcade Fire, which may just be enough to lure back avid concertgoers Kate and Alex.

Minka Kelly took her cute pup Chewie out in Beverly Hills on Thursday. She's been enjoying the warmer temperatures in LA recently, and even headed to the beach with her pooch when she wasn't working on her NBC series Parenthood. Minka's also juggling her big screen project, The Roommate, which will be released next month and has its big premiere tomorrow night. She started promoting the horror film with a sexy GQ spread and opened up about wedding rumors, though most of you seem to think she won't make it down the aisle with Derek Jeter.

The stars were front and center this week as awards season kicked into high gear, with both the Critics' Choice Awards and the Golden Globes. Natalie Portman was the woman of the hour at both, taking home acting statuettes for her work in Black Swan. Her fiancé, Benjamin Millepied, was by her side at the events, and other celebrity couples also showed their support for each other at the shows. Jennifer Garner and Ben Affleck made a Friday date night out of Critics' Choice, while Angelina Jolie and Brad Pitt wowed on the red carpet at Sunday's Globes. Fellow A-listers Kristen Stewart and Jennifer Aniston may have been absent from the festivities, but they each debuted a new magazine cover this week — Kristen scored the February cover of Vogue while Jennifer graces the latest Allure.
