Scarlett Johansson getting rid of her famous curves

New York, Mar 27 (ANI): Hollywood actress Scarlett Johansson seems to have forced herself into a rigid diet regime to get rid of her famous curves.

The Horse Whisperer showed off her "very slim" figure in a tight, black minidress at Moet and Chandon's "Tribute to Film" soiree at London's Big Sky Studios.

"She was talking to Thandie Newton about the rigid diet she's on," New York Post quoted a spy as saying.

According to a source, Johansson "was really working it".

Also present at the event were Joseph Fiennes, Eva Herzigova and Marc Newson. (ANI)
