We're not sure what Katy Perry is going to say when she hears her fiance Russell Brand's ultimate stag do fantasy.

Because eccentric Brit Russell got us a tad worried when he revealed that his fantasy stag do would include both Lady Gaga and Taylor Swift.

What the fudge?!

According to the Daily Mirror, Russell who has also joked that he's impregnated actress Helen Mirren, said:

“I'm gonna get Lady Gaga and Taylor Swift to perform a lesbian show on my lap...I'm gonna shrink them down till they're the size of dollies.”

Err...that is just disturbing Russell!

This isn't the first time Russell's done something out of the ordinary....
