Britney Spears has filed for divorce from Kevin Federline.

The 24-year-old pop star filed legal papers today in Los Angeles Superior Court, citing "irreconcilable differences" and asking for custody of their two children — 1-year-old Sean Preston and 2-month-old Jayden James.

Spears gives the date of separation as Monday, the same day she showed off her postpregnancy body during a surprise appearance on "Late Show with David Letterman."

The announcement comes roughly after two rocky years of marriage. Spears married Federline on Sept. 18, 2004, eight months after ending a 55-hour Las Vegas marriage to her childhood friend, Jason Alexander.
