NEW YORK - Rudy from "The Cosby Show" has grown up, and she's about to show off her life on cable TV.

Oxygen said Wednesday that it's developing a reality show about actress Keshia Knight Pulliam and her live-in boyfriend, Atlanta area entrepreneur Kaseem Penn. It will explore what it's like being young, rich, single and co-habitating. No air date is set for the show, titled "Keshia and Kaseem."

Come summer, Oxygen will premiere a series called "Dance Your Ass Off." It'll be hosted by Marissa Jaret Winokur, who won a Tony for her performance in "Hairspray" as Tracy Turnblad, the full-figure teen who yearns to dance on a TV show in 1960s Baltimore; she's also appeared on "Dancing With the Stars." In the Oxygen show, competitors try to show off their dancing skills and lose weight _ sort of like "The Biggest Loser" with rhythm.

Since being bought by NBC Universal, Oxygen has been seeking an audience of trendsetting women, generally aged 18 to 34. Its theme is "live out loud."

Oxygen's most visible stars are Tori Spelling and husband Dean McDermott, who are filming the fourth season of their own reality series based on their lives. The network announced a broad development deal with the pair to make a TV movie, a makeover show that features the couple, and Web content based on Spelling's book "Mommywood."

The network will have two other new series later this year. "Addicted to Beauty," called a "docu-comedy," is about the staff of a plastic surgery facility in California. "The Naughty Kitchen with Chef Blythe Beck" follows the life of the 29-year-old, Dallas-based chef.
