Britney SpearsBritney Spears is apparently getting tired of husband Kevin Federline’s endless spending - particularly when he uses the money to go partying with his friends.

“Kevin asked Britney for money to go to Las Vegas in two weeks, and she shut him down,” a inside source has told the New York Post.

“Britney told him that she won’t be funding his trips with his friends any longer - he used to fly everyone out on her dime. The monthly allowance she had put him on seems to be disappearing after only one week.”
