Turns out she’s a pro at that, too, as this clip from the upcoming Lip Sync Battle proves.
The 26-year-old Dancing with the Stars judge got plenty of judgment from her older brother after she performed a rather risqué version of “I Just Had Sex” by The Lonely Island.
The five-time Mirrorball Trophy winner – who’s used to doing a bit of dirty dancing himself – shot a shocked look at the performance before covering his eyes and ducking his head the further his sister goes with two shirtless dancers backing her up.
Lip Sync Battle airs Thursdays (10 p.m. ET) on Spike.
