While Lady Gaga, Jennifer Lopez and Kenny Chesney all brought their A-game to the iHeartRadio Music Festival on Saturday (Sept. 24), Nicki Minaj's colorful, predictably manic performance of her smash single "Super Bass" served as one of the night's many highlights. After commanding the stage at the MGM Grand in Las Vegas, Minaj credited the success of "Super Bass" to an unlikely source: country star Taylor Swift, who performed the song with the rapper at a Los Angeles show last month.

"I want to publicly say again that Taylor Swift really launched that single into another stratosphere, with just tweeting about it and rapping it and stuff," says Minaj of "Super Bass," currently at No. 9 on the Hot 100. "I performed it with Taylor, and she's so cute, and she's like a big bowl of ice cream!"

Minaj ran through hits like "Did It On Em," "Moment 4 Life" and "Where Them Girls At" at the inaugural iHeartRadio fest, and although she didn't unveil any new music from her in-the-works sophomore album, the rapper reiterated that her alter ego, "Roman Zolanski," would have a key role on her next full-length.

"All I can say is that Roman will definitely be a humongous part of the follow-up to 'Pink Friday,'" says Minaj in her trademark Roman accent. "All I can say is that I'm working on it, and the fans are gonna get their life and then some."
