Carly Rae Jepsen is the gift that just keeps on givin’, guys — the girl cleaned house tonight at the 2012 MuchMusic Video Awards! The Canada native took home the award for Video of the Year for ‘Call Me Maybe,’ and it was one of the night’s biggest awards.

In true diva style (no, we don’t think Carly’s actually a diva), she did a wardrobe change from her performance earlier in the evening. From a short red dress, to a stunning and mature long black number with thigh-high slits on either side (which totally reminded us of the dress Shenae Grimes wore earlier), she accepted the award from ‘Glee‘ star Chord Overstreet.

We were too focused on her outfit to actually make note of what she said in her speech, but we did hear her thanking Justin Bieber! Bieber announced in February that Jepsen had been signed to Schoolboy Records, the label that’s run by his manager Scooter Braun, so it sort of makes sene that she would mention him in her speech. Having Justin Bieber as your mentor of sorts isn’t too shabby.

Congrats again to the queen of the 2012 MuchMusic Video Awards, Carly Rae Jepsen!
