Jennifer Lopez: Dsquared2 Dinner Following the AMAs 2013!

Jennifer Lopez looks glam in a black dress while attending a dinner hosted in her honor by Dean and Dan Caten of Dsquared2 on Sunday evening (November 24) at the Chateau Marmont in West Hollywood, Calif.

The 44-year-old entertainer was joined by BFF Leah Remini as well as Rob Pattinson, who was accompanied by a photographer friend. The dinner turned into a dance party with fun 80′s and 90′s music.

“Rob only hung out with the group that he came with,” a party goer tells Just Jared. “He didn’t mingle with any of Jennifer‘s guests.”

Earlier in the night, Jennifer was in attendance at the 2013 American Music Awards, where she performed a tribute to the late Salsa dancer Celia Cruz.
