"I'm a socialite!" she said without revealing too much about the new show. "It's exciting! I'm making the move into scripted. I feel comfortable paying the socialite. I'm good at it!"

Fans of the New York Housewives, which is returning for its fourth season on April 7, will see a "shift in friendships and new alliances," said Luann.

"I think it looks very exciting and there's a lot of drama going on. I think people are invested in our characters."

Last year it was Jill Zarin who butted heads with the leading ladies, and this year it looks like the new antagonist is Ramona Singer.

"Ramona lets a lot of things fall out of her mouth and I think she's going to have a harder time getting away with that," Luann confessed.

"I think some of us have issues with Ramona and some of us don't-everybody knows Ramona and she's always somewhere involved in the drama and I think you're going to see her bumping heads with some of us this season.

"I try and keep the peace which isn't always easy. But I'm not push-over, if I have something to say I say, I just say it differently.

Luann has her own set of personal adventures this season, including a studio visit with music legend Natalie Cole, a Sex And The City-style girls-only getaway to Morocco, and finding love with her hunky new beau Jacques Azoulay.
