For fans hoping to hear what Avril Lavigne and Nickelback frontman Chad Kroeger were up to in the recording studio other than falling in love, soon they will get the chance to hear the song they created together.

L.A. Reid told Billboard that Lavigne's upcoming album, which features a "really good record" with her fiancé, will be out by the beginning of 2013 at the latest.

"We're in the mixing process now and I expect to release it very soon," Reid added about the "just-finished" record. "I'd like to get it out this year, but time seems to be flying. If we don't, it will be top of the new year."

(Kroeger and Lavigne announced their engagement last month. They met while they were working on the album earlier this summer, the follow-up to 2011's Goodbye Lullaby, which featured some help from her ex-husband, Sum 41's Deryck Whibley.)

Lavigne spoke to MTV News last year about reuniting with "X Factor" judge Reid at Epic Records. He discovered her and launched her to superstar status in the early part of the millennium.

"It's really exciting for me, because L.A. Reid signed me. He met me when I was 15, and he signed me on the spot. We did my first album together, and it was really successful and then what happens in the record industry, you know, changes are made," she told MTV News. "We didn't get to work together, and I was so bummed out, 'cause I never had that connection with anyone ever again, like, my whole career at the record company."

As for working with Kroeger, in the same interview, Lavigne made it clear she wanted to work with new folks on this album.

"In my new record coming up, I think I want to start off by working with people I've never worked with before because that's hard to do," she told MTV News. "When you don't know someone you have to go in and you write together and you're recording, you never know, you have to vibe together."

She added, "I'm trying to go for both sides. I love to rock out. I love to be crazy and have fun and have a more rock and roll aggressive side to me. But I also have a softer side and I wanted it also to be about my vocals... When you are having a good time making a record that always comes across in music. The energy's good so things flow better and that's what I'm excited about."
