Carly Rae Jepsen told MTV her lips are sealed regarding the track which will be released on her U.S. debut album this September. "The Justin song, I'm kind of sworn to secrecy on, because I think we want to release it together at one moment. But the rest of the album, I'm really excited for."

Since mum's the word on the Biebs, she opened up about another song on the album. "There's one particular song that I can't wait to share, called 'This Kiss,' that I wrote with Matthew Koma and RedFoo from LMFAO."

She pointed out the beauty of collaborating to create a sound different themselves as individuals. "The sound is definitely in my vein, but he's a really brilliant guy, and I think, if anything when a collaboration happens, it's a little bit of everybody that makes it what it is. So maybe not just me and not just him, but us together."
