LMFAO party rocked the stage of 'The Tonight Show With Jay Leno' last night, performing their latest single, 'Sexy and I Know It,' in skimpy Speedos.

With all the confidence in the world, SkyBlu and Redfoo rapped about being irresistible to the ladies, while a group of dancers supported the performance. Then, at the chorus of the duo's new song, Redfoo sauntered up to the front of the stage and pulled off his tearaway shorts to reveal a shiny Speedo.

But, not to be upstaged, SkyBlu also wore a junk-hugging number, only his came with a notable addition, which made us believe he had a garden hose in his pants.

'Sexy and I Know It' is the third single from LMFAO's sophomore album, 'Sorry for Party Rocking.' Although fans have heard the song online and on the radio, the track's official release date is Oct. 3.

'Sexy and I Know It' follows 'Champagne Showers' and 'Party Rock Anthem,' the latter of which hit No. 1 in over a dozen countries. The song sailed to the top of Billboard's Hot 100 chart, where it stayed for six consecutive weeks, and tied with Lady Gaga's 'Born This Way' for second-most weeks on top of the chart.
