The Rocket was joined by the Rolling Stones icon on Tuesday (November 21) as the pair were accompanied by their wives and friends to a fine dining experience at Scott's restaurant on Mayfair. They were snapped by cameras following O'Sullivan's premiere of 'The Edge of Everything' which will be available to watch on Prime Video in the UK and Ireland on Thursday (November 23).
The 47-year-old opened up about his life, including his struggles with drugs and alcohol and the imprisonment of his father who was locked up for 18 years for murder.
Ronnie O'Sullivan Sr opens up about the effect his time in prison had on the snooker great while his mother Maria is also seen in the documentary but the seven-time World Snooker Championship victor said his parents aren't big fans of being in front of the screen.
"My mum and dad are very, very private people. They don't really like that side of it," he said. Sam Blair - the director of the documentary - met O'Sullivan's mum as he said: "That was one of the reasons to get someone like Sam on board, because I knew my mum would like him, and he gained her trust.

"My dad's a little bit easier, ‘wherever you want son I'll do’, but with my mum, she's always more the cautious one. You can't have a documentary and not mention important things that have gone in your life, but I said to my mum, it's not a documentary about you and dad and how you grew up, it's more about me. So she was OK with it."
During the documentary, O'Sullivan Sr - who was found to have stabbed dad-of-two Bruce Bryan to death in a Chelsea nightclub - said he used to break down when he was on the phone to his son in prison and believed he was going to quit snooker.

"I didn't think he was going to play anymore, I thought it was over, I thought it was done, everything was over, I used to put the phone down, totally in bits. A lot of that was my fault. I blame myself for that, going to prison, it wasn't good for him. And he'd say he’d had enough, he wanted to put his cue down, done."
