Scarlett Johansson was nervous to be `new kid` on Iron Man 2

London: Scarlett Johansson was nervous about being "the new kid" on Iron Man 2.

The Mirror reports, while at the film’s world premiere in Hollywood, the actress said: "At first I thought I might feel like the new kid on the block, but I was so warmly welcomed by Robert and Gwyneth and Jon - I felt like I was inducted into the brotherhood.” She further said: "I’m now a master mixed martial artist, but I don’t want to let people know that because I’m afraid that they’re going to constantly challenge me to a fight or a dual."
