Lavigne was on hand at the VMAs to help present during the awards show.

In February, the pair first sparked dating rumours after being photographed on a dinner date at BOA Steakhouse in Los Angeles.

A month later, Lavigne and Mod were spotted with Megan Fox and Machine Gun Kelly on a double date.
