Following a performance, Ross brought in food from his restaurant Wing Stop, passing out chicken wings to the crowd.
“Rick brought actress Billie Lourd, models Jordyn Woods and Iskra Lawrence up on the stage to feed them,” says the spy. “He was hand-feeding Iskra wings.”
Ross performed “Hustlin’,” “The Boss” and “New Flame.”
Also at the party were Ashley Benson and Dylan Sprouse.
