It's the Battle of the Brits on Lip Sync Battle this Thursday, when British pop stars and besties Rita Ora and Charli XCX go head to head for the champion belt.

In a special preview clip from the "Doing It" collaborators' upcoming episode, Rita struts her stuff while mouthing along seductively to Right Said Fred's classic 1991 smash, "I'm Too Sexy."

After her display, fellow Brit Boy George, who acts as a guest DJ for the episode, says he "loved" the performance.

"It was Right Said Rita, all the way," he gushes in the clip.

Meanwhile, in a preview clip from Charli's performance, the "Boys" singer can be seen wearing Ed Sheeran drag while busting out a spirited lip sync performance of "Shape of You," booty-shaking included.

Charli and Rita's episode of Lip Sync Battle airs Thursday, March 29 at 9:30 p.m. EST on Paramount Network.
