Scarlett Johansson, the actress of such hits as "Lost In Translation", was stunned when she saw a picture of herself on a billboard where her chest had been digitally altered.

According to the Daily Record, Johansson nearly crashed the car she was driving when she looked up and saw the picture of herself. She said, "I was driving through Los Angeles and I look up and see the biggest photo of me I have ever seen in my life on a massive ad space.

"I screamed and slammed on the brakes. I couldn't believe it. It's very strange to see my cleavage the size of a brontosaurus. My breasts were huge. I had long hair and my goodness, I couldn't get past the cleavage."

Her new movie "The Island" which co-stars Ewan McGregor has not fared well at the box-office. The movie is about a pair, which is in a nightmare situation where human clones are bred to provide spare body parts.
