The 33-year-old musician is rumoured to be dating the 'Sk8er Boi' hitmaker and according to TMZ, he's had Avril's name inked on the back of his neck as a symbol of his affection.

The celebrity duo have remained tight-lipped about their relationship status so far.

However, a source told E! News that they've spent the last two months working on Avril's new album, which is set to be released later this year, and they've quickly developed a strong bond.

The music stars also worked together on the track 'Flames', which came out in January.

Avril, 36 - who was previously married to Deryck Whibley and Chad Kroeger - was recently reported to have fallen for Mod after working with him in the recording studio.

A source explained: "Working together has brought them closer and Avril has a history of falling for people that she works with. She falls in love with them for their musical creativity and expression.

"Her working relationships often turn romantic."

Avril and Mod - who previously dated Disney star Bella Thorne - have relished spending time together in the studio amid the coronavirus crisis.

The insider shared: "Avril and Mod Sun have been spending a ton of time together and getting to know each other better."

Avril previously insisted she hadn't given up on love, despite going through two divorces.

The 'Complicated' hitmaker - who split from her previous boyfriend, Phillip Sarofim, in January 2019 - claimed she hasn't allowed heartache to undermine her faith in true love.

Asked if she'd like to get married again, Avril replied: "I don’t really care so much about that; I just care about being in a healthy relationship and just being happy."
