The pop princess filed for divorce Tuesday from her husband, former backup dancer and aspiring rapper Kevin Federline.
The Los Angeles County Superior Court filing cites "irreconcilable differences."
In the divorce papers, which do not mention a prenuptial agreement, Spears asks for custody of the couple's two children, with visitation rights for Federline. The filing does list as separate property, and thereby off-limits to Federline, "miscellaneous jewelry and other personal affects," earnings and other assets to be determined later.
Spears' declaration that she and Federline had no community assets indicate the pair had a prenuptial agreement and don't want to disclose to the court their divorce settlement, said Leon Bennett, a divorce attorney.
The filing also stated the marriage occurred Oct. 6, 2004, a few weeks after a widely covered wedding ceremony.
Federline at the time explained the two ceremonies by saying that the couple had moved the wedding date up to throw off the media, but doing so did not give their lawyers time to finish their prenup.
A message left with Spears' attorney, Laura Wasser, was not immediately returned.
Spears married Federline eight months after ending a 55-hour Las Vegas marriage to her childhood friend, Jason Alexander. Her second marriage has provided endless fodder for tabloids, which have speculated frequently that the union was in trouble.
Federline's attorney, Mark Vincent Kaplan, issued a statement declining comment.
"There is no statement at this time as requested by Mark's client, Kevin Federline," said Michael Sands, spokesman for Kaplan.
But in an interview with The Associated Press two weeks ago, Federline had nothing but praise for Spears.
"Her influence on me has been really big," he told the AP. "She's a strong woman and she knows what she wants out of life and that helps build a strong man. I look up to you baby."
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 leaving the show she released her debut album, "Baby One More Time." In a video for the title track, Spears dressed provocatively in a school uniform and cemented her reputation as a sex symbol. Yet, throughout a years-long romance with Timberlake, Spears always proclaimed her chastity.
By 2003, Spears had fully embraced her sex-charged image, sharing an open-mouthed kiss with Madonna during the MTV Video Music Awards. Also in 2003, Spears gave an interview to W magazine in which she revealed she had lost her virginity to Timberlake.
Federline appeared in the movie "You Got Served" and performed as a backup dancer for singer Justin Timberlake, Spears' former boyfriend. He was previously involved with actress Shar Jackson of TV's "Moesha." Federline and Jackson have two children.
