Britney Spears has filed a petition for divorce from thug husband Kevin Federline.

TMZ obtained the legal papers, filed today in Los Angeles County Superior Court, citing “irreconcilable differences.” In her petition, Spears asks for both legal and physical custody of the couple’s two children, one-year old Sean Preston and two-month old Jayden James, with Federline getting reasonable visitation rights.

Brit seems to have taken my advice from earlier this morning that the last step to a come back would be to get rid of K-Fed.

Significantly, Britney lists the date of her marriage as October 6, 2004. There was an uproar around the time of the wedding because the highly publicized “secret” ceremony was held on Sept. 18th, leading many to question the validity of the ceremony. Now the divorce documents indicate that the lavish ceremony was not the official wedding.

Three cheers for Britney and hopes that this will bring her happiness.  See the how Britney brought sexy back last night on Letterman.
