In an exclusive preview of an upcoming episode of Spike’s Lip Sync Battle, the siblings make some unexpected – and blush-inducing – choices as they show off their triple-threat talents.
As the good book says, hips don’t lie. And neither do the shocked facial expressions of Julianne’s “straight-up traumatized” big bro and host LL Cool J.
Lip Sync Battle premieres Thursday at 10 p.m. ET on Spike.
