Fatboy Slim, whose birth name is Quentin, has revealed that he grew up in an open relationship household with his parents, describing it as having "two mothers and two fathers" all living together.

The DJ, formerly married to broadcaster Zoe Ball, explained on BBC Radio 4's Desert Island Discs that his parents, environmental consultant Ronald Cook and teacher Ros, chose to stay together for their children but pursued separate relationships while living in the same house.

"They wanted to stay together for us kids, but they didn't like each other any more," Cook told the program. "So one day they stopped rowing and just had other partners. They were in an open relationship, living in the same house."

He recalled that this arrangement seemed normal to him and his siblings at the time, but they later realized it was unconventional when speaking with peers.

Cook also touched on his birth name, Quentin, which he received in the 1960s and was derived from the Latin word for fifth, as he was the fifth member of his family. He noted that before Quentin Tarantino became widely known, the name was primarily associated with the English writer Quentin Crisp, leading to him facing ridicule in school.

He adopted the stage name Norman Cook for his music career, stating, "I just wanted a really normal name. So Normal Norman just had a good ring to it."

Cook, who attended Reigate Grammar School with current UK political leader Keir Starmer, also spoke about his struggles with alcohol addiction. He shared that achieving sobriety 17 years ago was a significant challenge, partly due to relying on alcohol to manage severe stage fright.

He credited his ex-wife Zoe Ball with being instrumental in his decision to stop drinking. "All she said was, 'Oh, Norman,' but she said it in such a way... it was my wake-up moment," he recounted, indicating her comment prompted him to quit.

Following a period of rehab, Cook described initial performances as difficult due to persistent fear, but eventually regained his confidence during a concert in Japan where he felt a strong connection with the audience.
