Avril Lavigne showed up to the 2013 MuchMusic Video Awards looking so happy with her fiance, Nickelback frontman Chad Kroeger, but she looked even happier up on stage when she was performing her latest hit 'Here's to Never Growing Up.' 

The Canadian starlet took the stage in all black, with her smokey eyes and longer-than-ever blond locks popping against her leather jacket. As usual, Avril looked like a total rock star, working the stage and leading the crowd in a sing-along (via her glittery microphone) to the lead single from her forthcoming fifth album.

Later on, she invited members of the audience (we still can't tell if that was rehearsed or not...) to dance on stage with her. Overall, Avril's voice sparkled, and so did that gigantic rock on her ring finger.
