Following her late night high-rise birthday dinner on Tuesday night, Britney Spears spent yesterday buying Christmas presents for sons Sean and Jayden at New York’s FAO Schwarz toy store.

Accompanied by the boys, her parents and a bodyguard, the singer is said to have dropped hundreds of dollars on the toddling two.

An onlooker told OK magazine: “Each of the boys had [an employee] to walk around with, and they each had a huge metal trolley cart to fill up.

“They picked out hundreds of dollars worth of MacK Trucks, cement mixers and RC cars.

“Sean really fell in love with a car transporter, which he had taken out of the box so he could hold it everywhere he went.

“Jayden was most excited about a little blue plane, and cried when someone tried to take it away.”
