Gentlemen, start your engines . . . because Us Weekly is on tonight's nailbiter installment of RuPaul's Drag Race! For the second year in a row, Us' Entertainment Director, Ian Drew, joins the queens in the work room for a special challenge right up our celebrity-loving alley.

After introducing Ian, RuPaul says: "When you're famous, people scrutinize every inch of your charisma, uniqueness, nerve and talent. When you're a famous drag queen, you're under even more pressure to be un-spookable."

Enter the season six "Scruff Pit Crew" (read: hot, oiled-up guys in tight, tiny underwear) as Ru sets up the premise of the flash quiz (differentiating "biological" women from "psychological").

Watch the exclusive preview now! RuPaul's Drag Race airs Monday on LOGO at 9 p.m. EST.
