It's been an incredible year for Avril so far. She has enjoyed success with her new album Love Sux and celebrated getting engaged to Mod Sun.

The musician dropped to one knee in Paris in April, with Avril sharing the sweet moment in pictures posted on social media. "Oui! Je t'aime pour toujours Dimanche. 27. Mars. 2022," she captioned the post which in English reads: "Yes I will love you forever, Sunday March 27. 2022."

In the photographs, she wore a slinky black gown that showed off her figure while Mod, real name Derek Ryan Smith, donned his signature leather jacket as he proposed with the Eiffel Tower in the background.

The post also featured a sun-kissed selfie of the two with her spectacular heart-shaped engagement ring that sparkled in the light against the bright pop of orange in her nails.

The two musicians are thought to have been together since November of 2020 but didn't make their relationship official until 2021 when they collaborated on the song Flames from Mod's record.

Avril was previously married to Sum 41 singer Deryck Whibley for three years, with the pair legally divorcing in 2010, and she later wed Nickleback star Chad Kroeger in July 2013 less than a year after dating him. They split in 2015. Mod Sun was previously married to Bella Thorne.
