Long before Kat Von D, Jesse James and Sandra Bullock were part of each other's romantic history, Kat and Sandy shared an odd connection ... via a tattoo. 

Back in 2001, Kat Von D -- a famous celebrity tattoo artist -- was asked to ink a permanent image of Sandra's face onto the chest of one of her male clients who happened to be a huge fan of "Speed."

So there you have it -- Kat Von D is now dating the ex-husband of a person she once tattooed on a total stranger.

How's that for full circle?
