K-Fed Turns Down Britney’s Birthday Invite

Britney Spears reportedly begged ex-husband Kevin Federline to celebrate her 26th birthday with her on Sunday.

The troubled singer is said to have made a late-night call to the Fedster, pleading with him to join her, as she partied until 4am with pal Paris Hilton.

A source close to the singer told Page Six: “She begged him to come out with her. Kevin reminded her that one of them needed to be a parent and take care of the boys.

“Then she hung up on him. Kevin said she was drinking.”

Meanwhile, Britney was almost replaced in her music video for new single Pieces of Me.

According to record company insiders, Jive Records were reportedly left furious after the troubled singer failed to turn up for the shoot, and threatened to give the $500,000 set to new singer Samantha Jade to use for her own video.

Inevitably Brit was there in a shot when she learned that a younger, hotter singer would be taking her place.
