Christina Aguilera

Taking a break from her busy music video shooting schedule, Christina and her hubby Jordan Bratman spent last night at the Mark Ronson concert. People all over the internet were calling it the Robbie Williams comeback concert, but not really. It was Mark’s concert, and Robbie Williams made a guest appearance.

Also in attendance were Nicole Richie, her fiance/boyfriend/hubby to be Joel Madden, and Mischa Barton. (for their pics, follow the jump.)

Look how cute Nicole Richie looks with her growing belly!

Mischa? Not so much in those shorts. Ah, well. She’s generally a fashion miss anyhow!
