The reason for her slim toned figure is all down to healthy eating, keeping a mostly vegan diet and running, Mischa Barton has reportedly been telling her friends.

The 25-year-old has been telling friends that her key to staying slim is "eating really healthy, keeping a mostly vegan diet and running," the New York Post reported.
Barton was spotted at Prime 112 Thursday night having a light dinner with friends and later at the W South Beach for drinks.
