According to a source, Federline now has "no qualms" about sharing custody. The deal just needs to be approved by a judge, reports express.co.uk.
Federline won custody of his sons after Spears’s public meltdown in 2008.
Meanwhile, Spears is set to take her kids on her "Femme Fatale" comeback tour which kicks off in June. She will be accompanied by her current agent boyfriend Jason Trawick.
