In this week's Billboard cover story article Jason Derulo talks fitness, his post Jordin Sparks love life, and his all-star-filled new album.
On life after Jordin:
"I do get tired of playing nice," he says. "Especially when people think I did something wrong, or that she broke up with me. But it's so behind me."
On his new album:
"You can't pull me out of the studio," says Derulo. He estimates he and his collaborators wrote more than 100 tracks for the new album... . "Songwriting is a muscle," he says happily. "The more you do it, the better you get at it."
