Kevin Federline has reportedly filed a court order to show cause for primary physical custody of his two sons with ex-wife Britney Spears. The papers were filed in LA Superior Court earlier today. When the former couple's divorce was finalized two weeks ago, 50/50 custody was agreed to, but a source close to Federline hints he is worried about Spears exposing Sean Preston and Jayden James to "unnecessary risk." The would-be rapper's attorney "hopes to get Kevin primary custody."
