Carly Rae Jepsen has long been teasing fans about her collaboration with Justin Bieber. And, if they thought they'd learn something new about the track as she inches closer to the release of her debut album this September, they'd better think again.

"The Justin song, I'm kind of sworn to secrecy on because I think we want to release it together at one moment," Jepsen explained to MTV News about the track's rollout. "But the rest of the album, I'm really excited for."

While she didn't want to say much about that duet, Jepsen did have more to say about her work with LMFAO's RedFoo. That song, she shared, might be her favorite 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 explained. "[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."

In addition to being a bit secretive about the tracks on the record, Jepsen revealed she is also full of a number of other feelings. Admitting a range of emotions including pressure and anxiety, she said, "The main winning one is excitement. I just feel really lucky to be able to do this. I've been writing since I was 17, and to finally have an audience ready to hear some of that is really, really exciting for me."

Jepsen said her album will reflect more the woman she is now than the girl she was all those years ago. "There's one or two song lyrics or melodies that have been taken from previous years," the "Call Me Maybe" singer said, "but most of the music is very new, and actually a lot of it is based on this experience of what I'm going through right now."
