Britney Spears has been granted permission to celebrate Thanksgiving with her two sons - albeit a day before the U.S. holiday itself (22Nov07). The troubled pop star will be allowed to see her young boys Sean Preston, two, and Jayden James, one, on Wednesday (21Nov07), after her lawyer Anne Kiley managed to negotiate the deal with Kevin Federline's attorney, Mark Vincent Kaplan last week (ends16Nov07). The two legal representatives are also reported to be in the process of working out a deal for the Christmas holidays, according to TMZ.com. Spears is locked in a custody battle with ex-husband Kevin Federline, after she was stripped of physical custody of the boys last month (Oct07). She is currently entitled to three court-monitored visits per week.
