Julianne Hough Performs ‘I Just Had Sex’ On ‘Lip Sync Battle’

There’s kissing your sister, and then there’s listening to your sister sing about having sex.

But wait, there’s more.

Such was the painstaking (yet hilarious for the rest of us) experience for Derek Hough as he watched sister Julianne Hough perform The Lonely Island’s “I Just Had Sex” in a new “Lip Sync Battle” preview.

In the latest episode of the Spike TV series, which airs May 14 at 10 PM, a mortified Derek looks on as Julianne performs the raunchy hit, sung from a man’s point of view.

“A woman let me put my penis inside of her,” Julianne lip syncs, as two shirtless men dance next to her on stage and Derek gasps off-stage. “I just had sex and I’ll never go back… To the not-having-sex ways of the past.”

“A girl let me do it, it literally just happened,” she later adds, as she performs the song made famous by Andy Samberg and The Lonely Island crew as a 2011 “Saturday Night Live” digital short, featuring Akon.

Might we get an Akon cameo for Julianne’s racy performance?!?

Other notable “Lip Sync Battles” have featured Dwayne Johnson vs. Jimmy Fallon, Anne Hathaway vs. Emily Blunt, and John Krasinski vs. Anna Kendrick.
