Yesterday the sad news that Rolling Stones legend Charlie Watts had passed away aged 80 shocked the world.
The musician achieved international fame as the rock band's drummer for nearly 60 years.
Although he was known across the world, he kept his personal life very private.
Unlike his bandmates Mick Jagger and Keith Richards, Charlie preferred to stay out of the limelight.
Charlie even kept his personal relationships hidden from his friends for a time – and didn't tell them he had got married.
Between 1962 and 1963 Jagger, Richards and Brian Jones lived together in a party flat in Chelsea, London, with Watts and Bill Wyman often staying over.
The flat was reportedly very dirty, with empty bottles and dirty clothes all over the place – but it became an important place for the band to bond and listen to music.
When the Stones released the hits Come On and I Wanna Be Your Man, Watts moved into an apartment overlooking Regent's Park with his then-girlfriend Shirley Shepherd in 1964.
The drummer met Shirley in 1961 during the first rehearsal with Alexis Korner's Blues Incorporated, where he played as a drummer while working a job at an advertising agency.
The duo tied the knot in 1964, while Jagger, Jones and Richards were out in town in London.
According to The Independent, Watts didn't tell them to begin with because he was concerned that this would alienate the group's teenage female fans.
He decided to hardly tell anyone about it to begin with – including the band and their manager Andrew Loog Oldham.
Their marriage remained solid until his death.He was faithful to his wife Shirley, and is said to have consistently turned down female fans on the road.
They were even reportedly invited to the Playboy Mansion, but he was more interested in Hugh Hefner's game room than getting it on with groupies.
He said: "I've never filled the stereotype of the rock star.
"Back in the '70s, Bill Wyman and I decided to grow beards, and the effort left us exhausted."
The couple went on to have daughter Seraphina in 1968.
Explaining the secret to his long marriage, he told NME: "Because I'm not really a rockstar.
"I don't have all the trappings of that. Having said that, I do have four vintage cars and can't drive the body things.
"I've never been interested in doing interviews or being seen. I love it and I do interviews because I want people to come and see the band.
"The Rolling Stones exist because people come to the shows. There’s nothing worse than playing in a club with three people sitting in the front – one’s your girlfriend and the other’s your mate – and that’s the audience.”
