Johnny Depp testifies in his defamation case against ex-wife Amber Heard. The actor claims he made a call for the actress to help with her 'Aquaman' audition. Depp also explains what information he gave to Heard about the Kate Moss incident. The model testified on Wednesday that while she slipped and fell down a flight of stairs in Jamaica during a vacation with Depp in the 1990s, he had nothing to do with it. Moss adds that Depp tended to her after her fall and ensured she received medical aid.
