Andy Cohen, Danielle Staub

Andy Cohen is Mr. Bravo. The network's programming executive, whom you may recognize from the Real Housewives reunion shows, will host his own late-night show starting Friday morning at 12 am/ET. In the live, half-hour series, Watch What Happens: Live, Cohen and his guests will tackle user-generated questions focusing on anything and everything pop culture. His first guest is none other than New Jersey housewife Danielle. Cohen talked to us about what he plans to ask her and who else we can expect to see.

TVGuide.com: How would you describe the format of the new show?
Andy Cohen: It's a combo between the reunion shows and Playboy After Dark with interactive elements. People are going to call in, email, Facebook and Twitter their questions, which we'll be able to take from everybody and anybody live. We'll talk about what's going on in that week of pop culture, what people want to know, and anything they want to talk about.

TVGuide.com: Who can we expect to see as guests?
Cohen: It's Bravo and beyond. This week is Danielle from Real Housewives of New Jersey and the cast-off from Fashion Show. And we'll have Sarah Jessica Parker on the phone. We're going to play "Stump Carrie Bradshaw'" with her, do some Sex and the City trivia and talk to her about her new show on Bravo. Next week we're really excited because we'll have Isaac Mizrahi, Kelly Ripa and Mark Consuelos.

TVGuide.com: What do you plan to ask Danielle?
Cohen: As much as we got to in the reunion show, there is a lot people still want to know. Hopefully we'll get [those questions] answered tonight. I think what Caroline accused her of [at the end of the reunion] is what everyone is still wondering. I have a sense, but it's not for me to say. Plus more information has come up since the reunion show — the Smoking Gun came out with a bunch of documents about her past and there's been a sex tape. We've gotten a lot of questions already [from people] so it should be interesting.

TVGuide.com: How did you get into on-camera work as an executive?
Cohen: It started out with my boss asking me to do a blog, and then she was obsessed with doing a live show on the web that followed Top Chef. And at that moment I was doing a lot of random pop culture punditry on various shows. Then she said I should host the online show, and we were looking to host a Real Housewives of Orange County reunion show. So this really became a spinoff of the online show.
