O Canada! Avril Lavigne is hard at work on her next album, and she's working with fellow Canadian, Nickelback frontman Chad Kroeger, on some tracks.

Lavigne tweeted a photo of herself with the 'Gotta Be Somebody' singer on Tuesday (Feb. 28), writing:

They look so happy! Earlier she'd teased her followers, offering, "I'm in the studio...... Who am I working with???? He's Canadian." (We were honestly thinking of Justin Bieber!)

Av's been keeping herself pretty busy lately, even outside of the studio. When she and beau Brody Jenner aren't dodging breakup rumors, she's busy with her designs, including a new nail art line. “Spring 2012 is a full lifestyle collection — we have footwear, eyewear, swimwear, bags and men’s clothing [as well as women’s clothing. Having the nails is great because it kind of completes it all.”

In addition, Lavigne's in talks to mentor on 'X Factor.' She was a protege of judge L.A. Reid, and when she heard that two seats were open, she jumped at the chance. Lavigne had her “people” reach out to the ‘X Factor’ team to convey her interest in judging, with a source saying that since Lavigne entered the business at such a young age, she feels like she’d be a good coach for the younger kids on the show. We think she'd be great!
