kevin Federline's new tattoo is dedicated to baby's conception

The Polynesian tribal belt tattoo on his back depicts the creation of life and features a fetus in the middle.

And though he gamely went ahead with having his back tattooed, K-Fed revealed that the experience had been “pretty [bleep]ing painful”.

"It's got the suns and the ocean and then the stars on my shoulders. It follows my wife-beater (vest) line. You can't see it when I'm wearing a wife-beater... It was pretty [bleep]ing painful," Contactmusic quoted him as saying.
