She's the queen of doing talk-show interviews—and now she'll be on the other side of questioning.

Oprah Winfrey will visit Andy Cohen at the Watch What Happens Live clubhouse on August 15. It'll be her first appearance on the show ever. The episode will air live at 11/10c.

Excited? So are we!

Winfrey's appearance follows a series of high-profile interviews this year—and if history is any indication, expect some major OMG moments with her sit-down.

Cher opened up about dating Tom Cruise, Martha Stewart revealed she felt sorry for disgraced celeb chef Paula Deen, and Nick Lachey talked about the best thing about not having Joe Simpson for a father-in-law anymore.
