Avril Lavigne and Mod Sun break up a year after their engagement

Avril Lavigne and Mod Sun have broken up close to a year after the singers got engaged, her rep confirmed to E! News. Mod Sun's rep, however, told, "They were together and engaged as of three days ago when he left for tour so if anything has changed, that's news to him." The breakup comes after photos surfaced of Avril going out to dinner with Tyga and a group of friends at NOBU in Malibu, during President's Day weekend. But according to a source close to the situation, the two are "just friends." Hollywood's latest breakup will come as a surprise to fans after Mod Sun recently gushed about his fiancée in a personal chat. "I have found such a partner in this world to go through the chaos that life gives you," he told E! News' Francesca Amiker earlier this month. "I have found that person. I'm with a real grown woman who has gone through it all 10 times over and she makes me a better person." He also included Avril on his new song Shelter.
