Frankel opens up even more

It's 1 p.m. in New York, and Bethenny Frankel is in her pajamas yapping on the phone about her marriage, being a mom at 39 and just where Kelly Bensimon stands on the crazy scale (Frankel's diagnosis: "She's certifiable.").

Frankel shot to reality star fame with her acerbic wit on Bravo's "The Real Housewives of New York City." Now she's juggling diaper changing - she gave birth to daughter Bryn a few weeks ago - and book editing with promoting her spinoff, "Bethenny Getting Married?"

The new docu-series premieres Thursday at 10 p.m. and chronicles the daily minutiae of Frankel's life as she prepares to become a mother and marry fiance Jason Hoppy.

"This (show) just gets more micro, gets really into the details of my life," Frankel said. "It's not big blowouts over cocktails or charity events... it's more dedicated to the struggles I go through: being 39, getting engaged, getting pregnant, doing everything backwards."

Frankel says viewers will see her shop for wedding dresses while six months pregnant, the chaos of writing two books and the early arrival of her baby.

"I could have a C-section and not be on any pain medication, but you give me too small of a portion at the ice cream store and I may have a nervous breakdown."

The first episode sees Frankel trying to organize a housewarming party while searching for another assistant.

She added, "This is a time I really want people who are good for me and good for my family, and, like, I want clean energy and everything to be happy..."

As for her future on "Housewives," Frankel hinted her time may be coming to an end. "You're seeing my life here, so I don't know what I'd be doing there.... It's enough, really."
