According to court papers, NBA star Shaquille O'Neal's wife - Va'shaundya "Shaunie" O'Neal - filed for legal separation in Los Angeles County Superior Court on Monday. She cites irreconcilable differences as the reason for the split.

Shaq and Shaunie have been married for seven years, and have four children ages 3 to 9. She is asking for an unspecified amount of money for spousal and child support, and is seeking sole custody of the children with visitation rights for O'Neal.

The couple live in Florida, but Shaunie is claiming to be a resident of California, a state with more generous community property divorce provisions. She flew to Los Angeles and claimed herself a resident on November 8, just one day before filing the separation papers.

Shaunie and Shaq have split before. They originally filed for divorce in 2007, but reconciled after the dispute over whether or not he was hiding money from her.

The couple reportedly have a prenuptial agreement.
