Professor Heather? Yes, Carmen Carrera has joined the "Drag U" faculty for Season 2. And prepare to get coached by Glee's Coach Beiste (Dot Jones) when she huddles up with Ru in the teachers' lounge, too!

Summer's coming, but that doesn't mean that school is necessarily over, kids. Actually this summer, school is gonna be ovaaaaahhhh when RuPaul's Drag U returns to educate a whole new batch of real lady pupils who are in dire need of some fab drag-u-losity in their lives.

Returning on June 20th, RuPaul and her prancing professors of drag divadom (including Dean of Drag Lady Bunny) will commence to teach the children well all summer long! And they've lined up a fierce batch of your favorite Drag Race alumni and superstar guest judges for your educa-tainment!

New drag professors this year include past Drag Race champs Bebe Zahara Benet and Tyra Sanchez, as well as Season 3 starlets Manila Luzon, Carmen Carrera and Mariah! Past professors Jujubee, Morgan McMichaels, Ongina, Pandora Boxx, Shannel and Raven will also serve staff realness.

And among the roster of visiting professors/guest judges you'll find legends like Shirley Jones, Candis Cayne, Molly Ringwald, Carnie Wilson, Lynda Carter (Wondrous!), Charo, Glee's Dot Jones (see above) and other stunners! Can you handle it?

Let's hope. And to get ready, please watch the quick Cliff-Notes-esque preview of the Season 2 season below!
