Will Smith wants female fans to stop asking him to sign their breasts - because he doesn't want to upset their boyfriends.

The star says he hates signing fan's breasts because most of the time their boyfriends are witnessing the event reports Contactmusic.com.

He said: "Chicks asking you to sign their breasts is weird... to just pop out in a public place. Their boyfriend sees that I signed their t*tty. That seems strange to me."
