The 'Complicated' hitmaker had been on hiatus from the music industry after the release of self-titled record in 2013 and in the last two years she battled with Lyme Disease.

But now she has confirmed that she is to put out her sixth studio LP this year and the whole process has been like therapy for the pop rock chick.

Sharing her excitement at joining the label - which looks after her ex-husband Chad Kroger's band Nickelback, as well as, The Rolling Stones and Janet Jackson - she wrote on Twitter: "Incredibly excited to be a part of the @BMG_US family & working with them on the release of #AL6! So excited to share more with you guys! (sic)"

The 32-year-old beauty also shared a black and white video of herself playing the piano and talking about how emotional this record has been to make and how it came about by accident.

in the short clip, she said: "For this album I have a new team behind me and I've just signed with BMG. I've been working really hard on new music and it is a reflection of my journey over the last few years. At this point in my career and in my life, I just wanted to just put fresh energy around me and I feel like I've had somewhat of a rebirth in my life.

"I've been faced with a lot and gone through a lot emotionally.

The whole writing process has been therapeutic and empowering without trying to make an album, I'd made one."

Avril previously insisted she is "coming out on the other side" following her battle with Lyme Disease, which can affect the skin, joints, heart, and nervous system.

Sharing a picture on Facebook, she wrote at the time: "Overcoming Lyme Disease. Feels good to have my Dr. smile and tell me how much progress I am making. I'm coming out on the other side batches!!! ‪#‎Fighter‬ ‪#‎F**kLymeDisease‬ (sic)"
