Tonight at the 2012 MuchMusic Video Awards, stars posed for fun pictures on the red carpet with some very interesting guests on their arms. Katy Perry, Canada native Justin Bieber, fellow Canadian Carly Rae Jepsen and Selena Gomez -- most of whom are performing at this evening's show -- all hit the red carpet at the 2012 MuchMusic Video Awards in Toronto for some adorable, and is some cases, steamy pictures.

Katy Perry had one of the most memorable red carpet moments. Dressed in a gold and black gown with her purple locks flowing, the 'Wide Awake' songstress escorted a troop of "mini Katy's" around the red carpet with her. Each of the girls was dressed as a different character from her series of 'Teenage Dream' videos, making for some adorable and hilarious red carpet pictures.

Justin Bieber was also in attendance with little brother Jax, who clutched onto his big bro like a little Koala bear -- they were too cute! Surprisingly, the Biebs posed for red carpet pictures with his pal Carly Rae Jepsen (who was also pictured next to some super hunky male models), but failed to snap a pic with his girlfriend Selena Gomez.

On a side note, the Biebs looked super swagged out in all-black with gold-trimmed sneakers, and Carly Rae looked very sexy in a shiny black gown. Meanwhile, the always beautiful Selena Gomez dazzled in a gold mini-dress.

Check out these picture from the 2012 MuchMusic Video Awards and let us know who you think was the best dressed! Our vote definitely foes to the 'T.G.I.F.' mini Katy.
