Scarlett Johansson has been put on a diet by Gwyneth Paltrow. The curvy "Lost In Translation" star has lost over 14lbs since she began working out with her "Iron Man 2" co-star in preparation for the movie.

A source said: "The pair have been doing daily workouts with Gwyneth's personal trainer Tracy Anderson. Scarlett is also staying away from carbohydrates."

Gwyneth Paltrow says her schooldays were "salacious." The "Two Lovers" actress has revealed her time at The Spence School in New York - which is regarded as one of the top private schools in the U.S. - was full of scandal.

She said: "You know there were some salacious things that went on."

Gwyneth Paltrow has blasted critics of her website, claiming they "don't get it." The "Iron Man" actress insists those who have been negative about Goop.com - which is dedicated to health and "nourishing the inner aspect" - do not understand the site's message.

She said: "I think the people who are criticizing it or criticizing the idea of it, don't really get it, because if they did, they would like it."

Robert Downey Jr. is dieting to please his friend Chris Martin. The actor - who became friends with the Coldplay frontman after starring in "Iron Man" with Chris' wife Gwyneth Paltrow - has been shedding pounds in preparation for his title role in the upcoming movie "Sherlock Holmes."

He made the decision to slim down following pressure from Chris, who is a big fan of the Arthur Conan Doyle detective stories.
