Hollywood made a mass migration to Canada last night for the 2012 MuchMusic Awards. And the show locked down some killer hosts for the big night -- LMFAO, Katy Perry, Kelly Clarkson, Selena Gomez and Flo Rida. And among the high-profile guests were a trio of notable Canadian nationals -- Justin Bieber, Nelly Furtado and Carly Rae Jepson.

Although the show itself was pretty entertaining, the red carpet was where all the action was at. Biebs walked the red carpet with a very special someone -- no, not his GF Selena Gomez, but his lil' bro Jaxon. Selena arrived before Justin and paraded down the carpet solo. And it was no surprise that Katy was one of the red-carpet highlights, arriving with an entourage that consisted of seven little girls dresses up as "mini-Perrys." The girls sported some of Katy's most famous ensembles, which were absolutely adorable.

Call Me Maybe singer Carly also made a big entrance onto the red carpet, arriving in a blue convertible that was being polished by a few hot shirtless men. That girl knows how to roll in STYLE.
