It seems the pressure is beginning to crack Britney Spears estranged partner Kevin Federline.

After allegedly threatening to sell sex tapes of the couple to the highest bidder, and then being caught in a hotel room with an as-yet unidentified female, K-Fed - or Fed Ex as he's now to be known - has finally held his hands up. Well, he held one hand up anyway, middle finger fully extended, and screamed: F*** Britney! during a gig in Virginia.

All this comes from the man who is currently seeking custody of the couples two children.

Maybe a deep breath and a touch of Zen would be helpful for the 28 year-old rapper at the moment
