Nick Cannon Talks Mariah Carey & Nicki Minaj Feud in Hollywood
10/28/2012 AT 12:45 PM EDT
"Cannon arrived with a posse of four blinged out guys. They were all wearing lots of grills and jewelry," an onlooker tells PEOPLE. "He drove all of his friends to the event in a Porsche."
While walking the red carpet, Cannon was anything but shy about answering questions about his wife Mariah Carey's feud with American Idol co-judge Nicki Minaj.
"He kept using her full name when he referenced Mariah," the source adds. "It was almost like he was a fan as opposed to her husband."
Then it was time for Cannon to assume his role as deejay.
"Nick hyped up the party by playing all his favorite songs, including ones by Carly Rae Jepsen and One Direction," the source says. "The crowd was loving the music and Nick was dancing!"
A guest approached the deejay booth to request that Cannon play Minaj's hit song "Starships" but the America's Got Talent host "acted like he didn't hear the request," the source adds. "Clearly he was supporting his wife during her feud."
