The Curious Tail of Kingston Rossdale

Everyone already knew that Kingston Rossdale is a real swinger. And now it appears he’s taken it so far that he’s actually grown a tail.

The celebutot crowd’s reigning jokester was spotted with his mom, No Doubt singer Gwen Stefani, leaving a Beverly Hills medical building on Friday, sporting a growth sprouting out of his backside.

No word on whether they were at the doctor’s to see if anything could be done about his new appendage.
