LONDON: Actor Ashton Kutcher, who sports a nasty scar on his knee, says it was after a childhood crush accidentally shot him. “I was 12. I had an air rifle and there was this girl I really liked and I thought it would be romantic to give this girl this BB gun for Valentine’s Day. So I gave it to her and she shot me in the knee and I had to squeeze the pellet out and I still have the scar,” hollywood.com quoted him saying. The actor married Demi Moore in 2005.
