It's a old movie about the woman. She mostly steals (eg: diamonds) from museums and high-scale jewelry shops. Or from other robbers. She cannot be caught. I think she also changes her identity all the time. She robbed her old teacher.(didnt know that). Also she got pregnant from other robber. Movie maybe from the 80's or 90's (not sure though). THANKS

It sounds like it could be the one with Catherine Zeta Jones and Sean Connery? I forget the name I THINK it's Entrapment?. but I could be wrong
