Johansson laughs off 'Paltrow diet' claims

Scarlett Johansson has laughed off speculation that she has embarked on a low-carbohydrate diet in preparation for her role in Iron Man 2.

Tabloid reports suggested that the actress had lost around 14lbs working out with co-star Gwyneth Paltrow after becoming increasingly concerned about "younger, skinnier" competition.

Speaking to WENN, a representative for Johansson said: "The press is making something out of nothing. She is simply getting into shape for a very demanding, physical role in Iron Man 2."

Earlier this month, the star branded Hollywood as "weight-obsessed" but insisted that she was a "healthy person".
