Carly Rae Jepsen put out a few calls when it came to enlisting some upbeat A-listers to help her put the finishing touches on her September debut album. And, they called her back. No maybes about it.

In addition to her duet [article id="1689029"]with Owl City, "Good Time,"[/article] she also found some accomplices in other chart-toppers, ranging from [article id="1688409"]one half of LMFAO[/article] to the one and only Justin Bieber.

"The way my album has come together has been sort of a shock for me," Jepsen told MTV News. On her track with Redfoo, the "Call Me Maybe" singer explained, "It's really neat. We made friends and started working on a song together, and we actually started working on a majority of that song over the phone.

"Also worked with Jack [Antonoff, guitarist] from the band Fun., and that was sort of a random collaboration of us both really digging what the other person did," she continued. "And the last collaboration is a song with Justin Bieber. We're gonna do a little duet. And then the rest are sort of like, I think [article id="1689342"]'Call Me Maybe'[/article] is a pretty fair representation. It is pop, but there's also dance-pop and a little hint of folk-pop."

Obviously, Bieber is more than just a really famous dude she made a song with: He also happens to be her [article id="1682352"]boss[/article], and she said the track was a bit of a happy accident.

"It was a song that him and Toby Gad brought to the table and asked [me to record]," she recalled. "Actually, on my first introduction of Bieber, he was like, 'Do you wanna sing this song?' I said, 'Yes!' I love that track as well, so it was exciting."
