Scarlett Johansson is putting off plans to appear on Broadway — because she suffers from “crippling” stage fright, reports.

The actress admits treading the boards in New York is a dream of hers, but she has to overcome a phobia of performing live first.

The stagefright is made all the more surprising because Johansson happily appeared in numerous plays as a child actress.

She tells America’s Glamour magazine, “I would love to work on Broadway, but I don’t know that it would manifest itself in musical theatre ... I have terrible stage fright that I’d have to get over.

“(It is) crippling. Not as a kid. It came on when I was a teenager, and I think it somehow sticks with you.”

The actress is back on the big screen when she joins the Iron Man franchise for the second movie in the series.
