Los Angeles: Actress Amber Heard, who is currently locked in a bitter divorce battle with her estranged husband Johnny Depp, has reportedly lost "too much weight". The actress was supposed to fly to London this week for costume fittings for her upcoming film "Justice League". But the trip was allegedly cancelled because producers believed she has lost too much weight. She is said to have lost around nine kg due to stress, reports tmz.com. Heard filed for divorce from the "Pirates of the Caribbean" star last month amid claims of domestic abuse. With an age gap of 22 years, the couple got engaged in January 2014.
