Lisa Rinna: Keeping Husband Harry Hamlin's 'Mad Men' Role A Secret Was 'Torture' (VIDEO)

Lisa Rinna's husband Harry Hamlin landed a role on "Mad Men" this season as Jim Cutler, a partner at the ad agency that just merged with Sterling Cooper Draper Pryce. On HuffPost Live on Tuesday, Rinna talked about how hard it was to keep her husband's gig a secret until it aired.

When asked if she felt the pressure of Matthew Weiner's infamous code of secrecy, Rinna replied, "Yes! Are you kidding me? ... You get a script that says basically, 'If you talk about this, even with your wife, you're fired.' Forget it. It is very, very secretive. So I wasn't really supposed to know about it until right now." Later, she added, "Finally I get to talk about it! I couldn't talk about it for like three months. And I have the biggest mouth on the planet, so for me to not be able to talk about it has been torture."

Although Hamlin was initially ambivalent about the opportunity because he wasn't given any details about the role he was auditioning for, Rinna helped nudge him to try out anyway. "Basically I said ... 'It's Matt Weiner, you're going in.' So he did go in. He read for a different role. He read for the role of the swinging couple [which went to Ted McGinley] ... He didn't hear for a couple weeks, and then Matt Weiner said, 'I have another role for you.' But they wouldn't tell him what the role was and they wouldn't give him script."

I said, "'Guess what? You're gonna take it. You do it. You're just gonna do it, because it's Matt Weiner.' And he listens to me, thank God. And how fabulous is he on 'Mad Men'? And just you wait."
