Amber Heard’s sister, Whitney Henriquez, is speaking out in the wake of the actress’ loss in Johnny Depp’s defamation trial. On Monday, Whitney shared a public message of support for Amber on Instagram. She writes to her sister, in part, ‘I will always be proud of you for standing up for yourself.’ The ‘Aquaman’ star, who says she plans to appeal the verdict, was found to have defamed Depp in a 2016 op-ed. The jury awarded Depp $15 million in damages.
