Spears and Federline have two children: Sean Preston, who turned 1 on Sept. 14, and an infant son, Jayden James, born Sept. 12. Spears is seeking "legal and physical" custody of both.

She declared in court papers that she and Federline have no community assets, which indicates they had a prenuptial agreement and don't want to disclose their divorce settlement to the court, said Leon Bennett, a Los Angeles divorce attorney who does not represent either party.

The filing came a day after Spears, back in shape after the birth of her second child, made a surprise appearance on David Letterman's "Late Show" in New York by popping up behind him as he was sitting at his desk.

Born in Kentwood, La., in 1981, Spears got her first taste of fame at age 11 when she joined the "The All New Mickey Mouse Club" TV show. Her fellow Mouseketeers included future superstars Justin Timberlake and Christina Aguilera.

Five years after Spears left the show she released her debut album, "Baby One More Time." In the video for the title track, Spears, still a teenager, dressed provocatively in a skimpy school uniform and moaned "baby, baby, baby." Yet she proclaimed her chastity, insisting she remained a virgin throughout her four-year relationship with Timberlake.
