(CNN) -- It's over for Britney Spears and Kevin Federline.
CNN has confirmed that the pop singer, known for hits such as "Oops ... I Did It Again" and "Toxic," is divorcing her husband of two years and one month. Spears and Federline, one of the singer's former backup dancers, married October 6, 2004, according to the divorce papers.
TMZ.com reports that Spears filed legal papers Tuesday in Los Angeles County Superior Court, citing "irreconcilable differences." Spears is asking for legal and physical custody of their two children, 1-year-old Sean Preston and 2-month-old Jayden James.
The date of separation was listed as Monday.
Spears, 24, married Federline after a six-month courtship in 2004. In January 2004, she had married childhood friend Jason Alexander in Las Vegas, Nevada. That marriage was annulled after 55 hours.
Federline, 28, previously had a relationship with actress Shar Jackson. The union produced two children, one of whom was born two months before he married Spears. Federline recently released a rap album, "Playing with Fire."
The Spears-Federline marriage has been chronicled in detail in celebrity magazines since the pair tied the knot, with rumors of problems surfacing often.
