“We might be competing on the charts,” Sparks told The Hollywood Reporter of the duo’s respective albums, both due out in early 2013. “So we’ll see how that goes.”

Or maybe not, as Sparks was quick to concede, “You’re gonna win, babe. Don’t worry,” while Derulo promises to buy “a million of her albums” in the first week.

And while each artist is putting the finishing touches on their releases, the third for both, there still is one big decision to be made: Who gets which duet?

“We’ve recorded a couple of songs [together], and right now we’re just trying to figure out who gets which one on what album,” said Sparks.

Noted Derulo, who was on hand to perform on the AMAs preshow, “If it goes anything like deciding what I was gonna wear today, then it’ll probably be her deciding.”
