Less than a year after getting engaged, the pop-punk musicians have decided to end their relationship, sources close to the couple tell PEOPLE.
“Avril and Mod Sun have been on and off for the past two months, but are no longer together as a couple,” said an insider.
Lavigne, 38, and Mod Sun, 35, were last publicly seen together at a pre-Grammy event celebrating Julie Greenwald and Craig Kallman in Los Angeles.
