Kevin Federline has filed for primary physical custody of his two boys with his ex-wife Britney Spears.

The documents were filed in Los Angeles Superior Court on Wednesday by Federline’s lawyer, according to the source.

Spears and Federline’s divorce was finalized less than two weeks ago. At the time, the couple agreed to split custody 50-50 of Sean Preston, 22 months, and Jayden James, 10 months.

But a source close to Federline told PEOPLE that the would-be-rapper was worried Spears was exposing the boys to “unnecessary risk” and that his lawyer, Mark Vincent Kaplan, “hopes to get Kevin primary custody.”

I doubt K-Fed will be successful with his petition but it wouldn’t surprise me because of Brit’s continual off-the-chart behavior.
