Oprah Winfrey, who recently announced she would end her daytime talk show in 2011, will produce a new cable television series that centers on the sexual explorations of a Los Angeles housewife.

The series on HBO will be produced by Winfrey's Harpo Productions, reported the New York Post, which got the news from Variety. It is being written by Erin Cressida Wilson, who wrote Secretary, the film that helped launch the career of Maggie Gyllenhaal in 2002.

“TV's touchy-feely daytime queen will get down and dirty with the HBO series, which revolves around a married woman who suddenly leaves her husband and kids to act out her secret fantasies in LA's seamy underbelly,” reported the Post.

Winfrey has a production deal with HBO, which includes plans for a miniseries about the muckraking journalist Ida Tarbell.
