The MTV music awards 2013 kicked off with host Rebel Wilson singing Miley Cyrus's "The Climb," where she was joined by the cast to "Pitch Perfect" to sing a medley that spoofed last year's films. Brittany Snow, Anna Camp and Skylar Astin, along with a troupe of gymnastic dancers, joined Rebel Wilson in four songs not featured in the film.

The opener was a hit and 'Pitch Perfect'. Rebel could sing well and, surprisingly, the chubby actress could really bust a move.  The results are clear on Twitter; the opener was a hit!

The Australian actress started singing solo and then joined a multi-genre that featured Wilson spoofing last year's films while spinning nunchucks.

Twitter fans rejoiced in all of Wilson's overweight glory. Here are some users' comments:

"Best MTV movie awards opener ever"

But there were also some negative reviews that thought the opener was awkward and cringeworthy.  Some found it even to be a little boring and shut off their TV:

And the award for most awkward opener goes to the MTV Movie Awards #wtfdidijustwatch
