AM in the PM

Nicole Richie's former flame, DJ AM (real name Adam Goldstein) was spotted doing a little shopping on the night before Christmas at LA's Grove mall. He's bounced back quite nicely, moving on from Nicole to lovely model Jessica Stam. The two are quite the color-coordinated pair in black shirts and jeans. Proving you can take the model off the runway, but you can't take the runway out of the model, Jessica rocks some sexy stilettos with her jeans. So, did Adam trade up or not?
