Britney Spears' fiance is a father for a second time.

Kevin Federline's former girlfriend, actress Shar Jackson, delivered their baby Tuesday at an Orange County hospital, Jackson's manager told People magazine. The baby's sex was not reported and a call by The Associated Press to Spears' spokeswoman was not returned. .

It was the second child for Federline, a 26-year-old dancer, and Jackson, 27, who appeared on the UPN series Moesha. They dated for several years and already have a 2-year-old daughter.

Federline and Spears, 22, announced their engagement in June but have not yet set a date. They began dating a few months ago, after her Las Vegas wedding to childhood friend Jason Alexander in January. That marriage was annulled 55 hours later.

Spears has told People she plans to meet Federline's children and would like children of her own someday.

"I definitely want to have some kids," she said. "I see myself with four or five."
