DJ Mars and Viktar Duplaix kept a packed crowd rocking all night while we took to the dance floor with Omarosa and her boo Michael Clarke Duncan. Rahsaan Patterson popped in with publicist Sheila Eldridge, as Vincent Herbert and Tamar Braxton (of "Braxton Family Values") parked their big pretty Rolls-Royce Phantom outside to come share Jamie’s birthday. Tamar sang Jamie a live birthday song and gave her a bunch of love. She and Vincent are two amazingly humble and sweet people. Jamie hugged Brandy and Ray J’s parents, Willie and Sonja Norwood, and headed back to her favorite place in the party … the dance floor. Everyone had a blast and headed out at 3 a.m.
