Taylor Swift
, once again, rocked the red carpet!

On Sunday, stars came out in full force for the 2013 MuchMusic Video Awards in Toronto, Canada.

Taylor, Avril Lavigne, Demi Lovato, Ed Sheeran, Big Sean, Stephen Amell and Brittany Snow were just a few of the celebrities in attendance.

The "Begin Again" singer looked super sexy in her black and white Herve Leger mini-dress, and we love, love her bold red lip.

Not only does Swift win our vote for best dressed of the night, but the singer also took home the award for Fave International Artist of the Year -- go girl!

Taylor's fellow pop-princesses, Avril and Demi, definitely disappointed at the award show.

Avril stuck to her usual black, leather-clad style ... but it was the "Here's To Never Growing Up" singer's spiky metal crown that really threw off her outfit.

Lovato played it safe with a long-sleved black dress ... and her bleached blonde messy hair and nude makeup were not the most flattering look.
