Quite a few celebs showed up in their glad rags for the 50th Birthday Bash for designer Christian Audigier in L.A. last week includin Fergie who looked great in a contrasting pretty floral dress and bad girl leather jacket.

I love the green and beige dress, and the waist belt, but beige shoes woulda been better than black.

Mena Suvari went for top to toe leather for biker chick chic. She teamed the leather jacket and trousers with a vintage tee but glammed it all up with killer heels.

I'm glad she's got those hair extensions in though cos the hsort hair was not working for her!

Alesandra Ambrosio may be pregnant but she certainly doesn't look it! The supermodel wore a purple and blue ombre dress which looked like a bit of a sack on her. There are better ways to cover up a baby bump than that!
