When I first glanced at this photo, I wondered whether Oscar trumps Grammy in the groupie universe. If so, Usher should be worried (or grateful?) about how well his fiancee Tameka Foster and Jamie Foxx seemed to be getting along at DJ Irie's festivities in Miami this weekend.

On second glance, I realized that Jamie Foxx is just making fun of the size of her engagement ring. It was more interesting before, but I still wouldn't put it past her. Check out more pics from Miami after the jump.
