Ruby Wax recalls moment OJ Simpson called her up and said 'It's OJ, I did it' shortly after the pair had finished filming documentary where he pretended to stab her with a banana

Ruby Wax has recalled the moment OJ Simpson 'more or less' confessed to killing his former wife in what he claimed was an April Fool's joke. Ruby Wax alleged that after she and OJ Simpson had finished filming a documentary in 1998 that Simpson phoned her up on April 1st and said: 'It's OJ, I did it. Simpson was acquitted but later found civilly liable for the murder of his ex-wife Nicole Brown Pictured: The couple in New York in 1993 In a recently resurfaced video clip, Simpson pretended to stab Wax with a banana while making a bizarre violent noise as he grinned at the camera Wax has previously called the ex-NFL star, who was found liable by a civil court for stabbing to death his ex-wife Nicole Brown and Ron Goldman, 'the most complicated character on earth.' Wax, 70, is a British-American actress, comedian and television personality who interviewed Simpson, who she has called 'the most complicated character on earth,' 25 years ago Simpson's questionable joke came as she opened her hotel door to him, but the comedian claimed that he was initially looking for a knife 'After we finished filming, Simpson said to me that he has a surprise for me - and I genuinely was surprised,' Wax said. The morbid video re-surfaced on Thursday, as the world found out that the ex-football star and murder suspect had died after a short battle with prostate cancer Wax described their 1998 interview over 20 years later as a 'psychological midfield' and said the strange stabbing joke came after the interview OJ Simpson in a mug shot following his arrest in Los Angeles, California, US, 17th June 1994 Simpson had awkwardly joked about 'confessing' just weeks before his death in one of his final podcast appearances.
