The new teaser for Monday's episode of RuPaul's Drag Race is out—and it's a real shocker!

Fright queen Linda Blair is guest judging, along with Game of Thrones diva Lena Headey, a.k.a. the divinely sinister Cersei Lannister.

Those girls better be on their "game," 'cause Lena knows her drag: She and Peter Dinkelage ike to hit the gay bars when the finish promoting Thrones.

RuPaul's Drag Race airs Monday at 9pm only on Logo TV
