Johnny Depp has sued officials at the American Civil Liberties Union (ACLU) to force them to disclose how much money his ex-wife Amber Heard donated to them following their divorce. The Pirates of the Caribbean star has maintained that despite his ex-wife's claims she split her $7 million (£5 million) divorce settlement between the non-profit and the Children's Hospital Los Angeles, she actually only gave them a couple of hundred thousand dollars.
