TORONTO - LMFAO, meet the MMVAs.

The chart-topping Los Angeles electro-pop duo will co-host and perform at this year's MuchMusic Video Awards.

The hit-making pair -- consisting of Redfoo, whose real name is Stefan Gordy, and SkyBlu, a.k.a. Skyler Gordy -- have sent two singles to No. 1 in Canada, "Party Rock Anthem" and "Sexy and I Know It."

They'll join previously announced performer Katy Perry.

The MMVAs will be held June 17 outside Much headquarters in Toronto.

Additional performers and presenters are still to be announced.
