Fergie has been keeping busy: In addition to working with rapper Nelly on his upcoming album, Brass Knuckles, due June 24, she stars in his new video, which debuted Tuesday – and continues to deflect those nagging pregnancy rumors.
In the video for, “Party People,” Fergie goes glam – swinging above a runway, done up like a showgirl – then later goes side-by-side with Nelly as she sings two verses on the single.
Meanwhile, she’s done one-armed cartwheels on stage to prove that she’s not expecting, but the rumors, she says, “just mean that I need to get back to the gym,” the singer, who’s engaged to Josh Duhamel, joked last week. (See the video below.)
