Scarlett Johansson is a-la-nautrale and she wants the world to know it.

The buxom blonde has angrily hit back at reports that she is the latest Hollywood A-Lister to go under the knife.

Us magazine ran a report in their December issue, quoting the 23-year-old as saying "I definitely believe in plastic surgery. I don't want to be an old hag. There's no fun in that."

However Scarlett – who has previously been praised for her healthy body image – has forcefully denied she has had any work done.

"I have always been straightforward with the press regarding my body image” the Lost in Translation star said in a statement “I am very concerned that my fans (and perhaps even my employers) will feel mislead. 

"Thus, I feel compelled to take immediate legal action against Us Weekly." 

Her spokesperson added: “There simply is no truth to the story."

Johansson - who is dating Van Wilder star Ryan Reynolds - has just wrapped up two projects, He's Just Not That Into You, co-starring Jennifer Aniston, and the Woody Allen's latest flick Vicky Cristina Barcelona.
