'Supernanny' star Jo Frost has quit the hit ABC reality series to start her own family.

According to the New York Post, Frost will tape one more season of the series focusing on teen mothers.

"I have decided to hang up my cape," she told the newspaper. "It was a very conscious decision, through much reflection. But I need to create more balance in my life."

Frost has been traveling the U.S. and Britain since 2004, helping parents with unruly kids, but now she wants to focus on her own life and start a family. "Proper balance will allow me to date and have a relationship and look at my own future of having a family," she said.

Rod Lurie is no stranger to writing strong female characters. In film, he wrote and directed The Contender, with Joan Allen as a woman who was being considered for the Vice Presidency of the United States.

Then with Commander in Chief on ABC, he made Geena Davis the President and actually showed her in action -- until the show was canceled.

Lurie's working on another female-driven drama now for Showtime, but this time it's not about politics. Hillary Jones is the name of the show and the character, a police detective working vice in Los Angeles during the week, but moonlighting as a hooker in Nevada during the weekend.

She's not breaking the law, though, because prostitution -- as you and I know from the movies -- is legal there.
