Amber Heard testified in court that Johnny Depp threatened he could «kill» her after she claimed he grew furious for «telling on him» to his kids that he had fallen off the wagon and started drinking again.The actress took the witness stand on Wednesday and recalled a July 9, 2013 incident in the Bahamas, where the then-couple were said to be enjoying one last ride on his yacht with the actor's two kids — Lily-Rose and Jack — because Depp had sold the vessel to author J.K. Rowling.Heard claimed Depp was «upset he had to sell the boat,» and added that those emotions were compounded by Depp's drinking, which Heard claimed Depp tried hiding by pouring alcohol in coffee cups.
