Lindsay Lohan has stunned fans by confessing she's grateful for all of her legal run-ins, prison and rehab stints, and personal woes in the past two years - because they have helped her perfect her acting.

The troubled star, who has been panned for her latest role as Elizabeth Taylor in upcoming Tv movie Liz & DICk, admits she never has to worry about scenes in which she has to sob - because she just recalls one of many recent low points.

She tells the new issue of Us Weekly magazine, "(I regret) nothing, because then I wouldn't have been able to cry in scenes at the drop of a hat. I have it tattooed: 'Live Without Regrets'. I'm not saying I wanted to go to a jail cell, but I've drawn from all of it."

And now she's out to show her fiercest critics that she's got what it takes to become a great actress: "I want to be known as an actress, not a troubled starlet.

"People can think what they want, and the only thing I can do is prove them wrong."
