NBC Universal cable networks Oxygen and Bravo announced a slew of programming moves Sunday at the Television Critics Assn. press tour.

Oxygen unveiled several new series in development, the expansion of its original programming to a second night of the week and a new host for its freshman hit "Dance Your Ass Off."

Meanwhile, Bravo announced the series pickups of previously announced-in-development projects "Bethenny's Getting Married?" with "The Real Housewives of New York City's" Bethenny Frankel, and "Thintervention With Jackie Warner," starring the celebrity trainer from "Work Out."

Oxygen said it has tapped former "Spice Girl" Mel B to host the next edition of "Dance," which will return in the summer on a new night of original programming for the network, Mondays. The return of "Tori & Dean: Home Sweet Hollywood" will launch the new night in the spring.

"After the birth of my second daughter, I wanted to find a fun and effective way to drop the pounds and get back in shape," Mel B said. "I learned firsthand that dancing was the key to shedding off the pounds and keeping them off."

In addition to the previously reported "Jersey Couture," Oxygen is developing "Love Games," a spinoff of its successful "Bad Girls Club." The new series is a dating competition, with three former "Bad Girls" vying for the attention of eligible bachelors.

Other new shows include "Hair Battle Spectacular" (competition series featuring "fantasy hair" stylists), "House of Glam" (docu-soap set at celebrity styling company), "When Charlie Met Sarah" (docusoap following former "Bachelor" couple Charlie O'Connell and Sarah Brice) and "Fashion Drop" (a game show where contestants put their fashion knowledge to the test).

"We are unveiling a robust development slate filled with new content that expands into a variety of genres and formats," said Amy Introcaso-Davis, senior vp original programming and development for Oxygen. "We're continually listening to our audience and our goal, as always, is to give viewers a spectrum of choice across a diverse lineup of exciting concepts."

Bravo is also expanding its lineup, planning to grow its programming by 20% in 2010, plus announced new seasons for "Flipping Out," "My Life on the D-List," "The Real Housewives of Atlanta" and "The Rachel Zoe Project."
