Rebel Wilson paid reverence to her Australian roots as she thrashed out a bizarre musical number to kick-off the 2013 MTV Movie Awards in Culver City, California, on Sunday.

In her first gig hosting the event, Rebel Wilson began her star performance dressed in an Aussie-themed electric pink tracksuit, with koalas imprinted over her breasts.

The actress belted out some hit songs, including Eminem’s Lose Yourself and Alicia Keys’ Girl on Fire, before stripping down to a black leather cat suit and shaking her booty.

As Rebel Wilson closed out the performance with Macklemore’s hit-song Thrift Shop, an Australian flag fell down across the stage’s back video screen.

She then stopped to take a break and wiped herself down with a towel, while a topless man sporting a six-pack brought her a bottle of water.

Rebel Wilson thanked “hunky”, before a larger shirtless man appeared on stage to bring her chocolate.

After taking a bite, Rebel Wilson took time to thank “chunky”, before introducing herself to the star-studded audience – who looked visibly stunned by what they had just witnessed.
