Christina Aguilera and Jordan Bratman hit the town again last night, this time stopping by Villa in LA until the wee hours. She looked a little steadier on her feet this time and dare I say that Xtina looks prettier less done up than usual. There's a lot of speculation about Christina's nightlife habits these days — not that she and Jordan go out particularly often at all. Whatever the reason, the new parents deserve to let loose sometimes before getting back to their adorable little Max.

In her Uggs, tights, and knit cap, Sienna Miller arrived at LAX yesterday looking like she was ready to bid farewell to the California sunshine. She's heading home after wrapping G.I. Joe, and in true Sienna fashion she celebrated with her cast-mates at a prosecco-filled bash to mark the occasion. Now it's back to Rhys and London for Sienna, where they can continue that conversation about marriage and babies.

Ashton Kutcher brought his charm and a great blue shirt to The Late Show yesterday, where he cracked up Letterman with stories about growing up in Iowa, being a frat boy, Cameron Diaz's "superhero butt," and Demi's anti-aging leech treatment (don't worry, it confuses him too). Ashton has been looking great and turning on the handsome charisma out promoting What Happens in Vegas. He may have just turned 30, but he seems to be getting better with age. Between the cast's adorable chemistry and the promising trailer, I can't wait to see what exactly happens in Vegas.

After walking the red carpet at the Costume Institute Gala with Kate Moss in her design, Stella McCartney kept the celebrity party going on the West Coast with a screening of The Party. Nicole, Joel, Charlize, and Stuart were just a handful of the stars that came out to watch the movie in Stella's LA boutique. Stella's already set her sights on designing a dress for another starlet who wasn't in the house — she wants to make Scarlett Johansson's wedding gown even though the bride doesn't know it yet. She joked about her vision last night, saying, "You know, some kind of dodgy, black thing. Latex! Latex for Scarlett!" We wonder how Ryan would feel about that.

Rachel Bilson was thankfully back to her regular cute self, arriving home at LAX last night and greeted by her mom. Her Costume Institute Gala look won her worst dressed of the night, a title that little R-Bils probably isn't used to receiving. Luckily, Rachel will have a chance to redeem herself on the red carpet soon — she's hosting the Whitney's 2008 Art Party in New York on June 17. For now, Bilson should relax, enjoy Mother's Day with her momma, and plot her next surefire red carpet move.
