Wayne, 30, made his first public appearance since being hospitalized after suffering a seizure last month and was joined by Cash Money Records founder Birdman, reported People magazine.
"Lil Wayne looked healthy and fresh-faced. He sipped on water while holding court at a VIP table on Mansion's stage that overlooked the crowd," a source said.
Waynes had recently revealed in an interview that he is epileptic and "prone to seizures".
