Watch: Darren Criss Channels His Inner Mariah Carey for 'Lip-Sync Battle'

Darren Criss is the latest celeb to slay on "Lip-Sync Battle."

In a preview clip for tonight's episode, the Emmy Award winner is facing off against Jermaine Dupri in a Mariah Carey face-off – and Criss is here to win.

The "Assassination of Versace" star transforms himself into a mini Mimi, wearing a lace crop top, gold chains, a wig and a baseball cap. And of course, high heels. In the clip, Criss sings along to "Heartbreaker" while Dupri, who isn't in drag, goes for "Shake it Off."
