Britney Spears is reportedly planning to take ex-husband Kevin Federline to Disney World to celebrate their divorce.The 'Toxic' singer - whose divorce from Kevin was finalized on Monday - wants to whisk him and their two children, 22-month-old Sean Preston and 10-month-old Jayden James, off to the Florida resort. Although the couple are now officially divorced, custody arrangements for the two boys are yet to finalized. Britney is keen to be the primary carer and sees the holiday as the perfect opportunity to show Kevin that she is a good parent.A source said: "Britney loves Disney and thinks it's the perfect place for her and Kevin to show the children they are still a family."They are sharing custody at the moment, but Britney would love to get full custody but needs to win Kevin over."The pair, who split last November after a two-year marriage, have rowed constantly over the care of their two sons. Kevin, who has two other children from a previous relationship, previously claimed the 25-year-old pop star - who recently completed a stint in rehab for alcoholism - was too unstable to be a full-time mother. Britney's lawyer, Laura Wasser, says the pair are now willing to put their differences aside for the sake of Sean Preston and Jayden James. She said: "The divorce is final. Britney is OK with the arrangements. She would like to be with the kids more. She said that. She thinks Kevin would like that too."A custody hearing has been set for August 14.
