Sunday night's Much Music Video Music Awards in Toronto made headlines for a few reasons: 1. Lady Gaga sported turquoise-blue underarm hair 2. Justin Bieber played a prank on his girlfriend Selena Gomez and 3. Vampire Diaries' co-stars Nina Dobrev and Ian Somerhalder finally took their romance public.

The red carpet fashion was decidedly less dramatic, with most of the young stars opting for cute, yet safe dresses. Newly engaged Twilight star Nikki Reed, 23, posed in a black and white strapless design by Ronald Abdala, which she paired with black Casadei pumps.

Nina Dobrev, 22, wore iridescent emerald green strapless minidress with an asymmetric bow by Georges Chakra and nude Aldo shoes.

Selena Gomez, 18, who co-hosted the show with Colin Farrell, arrived in a beige Burberry Prorsum ruffled dress and purple Giuseppe Zanotti peep-toe pumps. (She had three outfit changes throughout the night.)

Pretty Little Liars' Shay Mitchell, 23, stepped out in a black strapless feather corset dress by Asos, with sky-high peep-toe pumps and a gold clutch.
