There's no way this story can be real, but it was originally reported in the UK's Daily Star on March 30, so unless they have an earlier Fools' Day over there, it's not an April Fools prank.
So, Pete Doherty is apparently cleaned up now, so much so that he's squeamish around needles. This was unfortunate when he decided to get a tattoo on his butt, and could only make it halfway through before begging the tattooist to stop. The result is a rather appropriate unintended word on his arse...
WASTE.
According to Charli Morgan's column "Goss," Doherty wanted to have Wasteland tattooed on his ass, after his favoriteTS Eliot poem. That could have worked, too, but "waste" is even better suited for its rump location.
