It's not complicated: Mod Sun and Avril Lavigne are very much a couple. 

The two were photographed holding hands as they entered West Hollywood steakhouse BOA on Feb. 12, where Mod Sun—whose real name is Derek Smith—was celebrating the release of his new album Internet Killed the Rockstar. The duo wore matching face masks with the name of the album written on them to the party. According to TMZ, the rapper also picked up $100 worth of flowers for the "Sk8r Boi" artist two days ahead of Valentine's Day.
