Nicole Richie and Diane Kruger both went with black, but mixed it up with sheer panels and hot cutouts at the 2011 UNICEF ball at the Beverly Wilshire last night in LA. This weekend is a big one for Nicole, since she and Joel Madden will be celebrating their first wedding anniversary — check out Nicole's and Joel's cutest pictures through the years. Brooklyn Decker was sporting a glow, fresh from her Bahamas vacation with husband Andy Roddick last weekend. The model-turned-actress is also looking gorgeous in the first trailer for What to Expect When You're Expecting. Diane Kruger had her own tropical vacation recently: she spent Thanksgiving lounging in retro bikinis alongside hot boyfriend Joshua Jackson.

Halle Berry flashed some strategic skin last night at the FiFi Awards, held at NYC's Lincoln Center. She posed for photos on the red carpet decked out in a revealing black Halston dress, and later caught up with friends like Nate Berkus and Mary J. Blige inside. It was an evening dedicated to honoring the best of the fragrance world, and Halle walked away with the Celebrity Fragrance of the Year statue for her work building a mini-empire with her Halle by Halle Berry, Pure Orchid, and Reveal. Fergie had husband Josh Duhamel on hand to pick up her New Celebrity Fragrance of the Year prize due to her 2011 release Outspoken by Fergie. Her bright yellow BCBG Max Azria dress added a pop of color to the proceedings, though Halle's main man, Olivier Martinez, wasn't able to attend.

Celebs toasted the Tribeca Film Festival last night during a cocktail reception at the W Hotel in Hollywood. The event begins on April 20 in NYC, but stars including Malin Akerman, Dax Shepard, Anna Kendrick, and Kate Walsh got an early start to the celebration of independent filmmaking at the packed LA party. Malin's Bang Bang Club, which also costars Ryan Phillippe, and Kate's Angel's Crest will be among the first movies to screen at this year's fest. Yesterday evening also marked one of Justin Bartha's first public appearances since his split from Ashley Olsen, and The Hangover star was spotted catching up and laughing with friend Zach Braff inside the soirée. Zach will be a featured speaker at Tribeca this year, and fans can already start submitting questions for the Garden State director online.

Halle Berry, Amy Adams, Melissa Leo, and True Grit's Hailee Steinfeld were together in LA last night for the annual Women in Film pre-Oscars bash. Though not up for an award this year, Halle Berry has had a busy few days of partying after hitting up a Dior dinner earlier in the week. Halle has, though, been a star of the Academy Awards before, making some of the most beautiful and fashionable appearances on the red carpet. Melissa, Amy, and Hailee are all going head to head as best supporting actress nominees, but there didn't seem to be much rivalry as they mingled at the event. We'll get to see who wins in their category, and many more at tomorrow's show — don't forget, we'll be live from the red carpet tomorrow, so watch here on PopSugar, and follow us on Twitter for breaking news and photos!

Cover Girl rounded up its beautiful spokesmodels last night for a bash after the People's Choice Awards in LA. Queen Latifah, fresh off hosting the show, attended the event with a brightly dressed Drew Barrymore, Taylor Swift, Ellen DeGeneres, and Niki Taylor. Ellen and Taylor seemed to be in especially great moods as they laughed their way past the photographers with Portia de Rossi. Taylor had lots to celebrate despite recently splitting from Jake Gyllenhaal — she ranked among the best dressed of the night and took home the favorite country artist honor. Check out the full list of winners! Lauren Conrad skipped out on joining the other lovely ladies on the blue carpet, but she turned out for the beauty brand's bash, as did her fellow MTV starlet Whitney Port.
