In February 2023, a source close to the couple told PEOPLE that they are "no longer together" after being on and off for months. This comes after the "Sk8er Boi" singer said "yes" to Sun's proposal on March 27, 2022. "It was the most perfect, romantic proposal I could ever ask for. We were in Paris on a boat in the Seine River. We had a violin player, champagne and roses. It felt like time stood still, and it was just the two of us in the moment," Lavigne told PEOPLE exclusively. Lavigne and Sun (whose real name is Derek Smith) first connected through music after collaborating on a song together in the studio. The "Complicated" singer was featured on Mod's 2021 single "Flames." In addition, he co-wrote and co-produced several tracks on her most recent album Love Sux, which came out in February 2022.
