The Federline Brothers: Big Apple Boys

Kevin Federline was spotted with his girlfriend Victoria Prince and two of his four children, Sean Preston, 4 next month, and Jayden James, 3 next month, at the Central Park Zoo in New York City today. Yesterday, we saw the Federline brothers going for a pedicab ride through Central Park with their mama, Britney Spears.

Kevin and Victoria were also frequently spotted with the boys during the European leg of Britney's "Circus" tour. Reportedly, the 27-year-old Lucky singer is paying her ex-husband $4,000 a week to keep her boys close.
