Kevin Federline's lawyer says Federline and his ex-wife, U.S. pop singer Britney Spears, have reached a settlement in their child custody battle.

The former couple have two toddler-age sons -- Sean Preston and Jayden James -- together.

Attorney Mark Vincent Kaplan told E! News all parties signed the agreement, which awards Federline sole legal and physical custody of the boys and gives Spears visitation rights.

"The case has been settled," Kaplan told E! News. "The court still has to approve it."
