Sir Elton John showed his caring side by advising pop sensations One Direction on the pitfalls of fame.
The piano tinkler is a former hellraiser and knows all about mixing with the wrong crowd after first tasting success. And he's hoping the band don't make the same mistakes he did.
He told The Sun: "If I had to give them advice I would say keep your original friends, keep good counsel with them. Try not to get too carried away with the clubs and all that c**p - but it's very difficult, because I did. If you enjoy it, you're young, it's a different thing, just go for it.
"Just make sure you don't get too drunk. What am I saying - I did the f**king same! Just go for it and see what happens. The thing is, it was just me. There are five of them together, they have each other to keep strong. Niall and Harry have now been in the paper a lot. I feel for them but I'm thrilled for them. They're also having a great time.
"Enjoy it, for f**k's sake enjoy it. If you don't enjoy it then there's no point."
Talking about Amy Winehouse, he adds: "It's incredible that it's been a year. It's one of the greatest tragedies. I saw her at the Shepherds Bush Empire when she'd just got married to Blake. It was a sensational show. I saw her afterwards and said, 'I've seen all the great singers, and you're up there with all of them'.
"She never really recorded that much. She made two albums and bits and bobs which came out on Lioness, that's it. You have to feel for her parents and family."
Sir Elt also revealed that he won't be one of the celebrities joining the Twitter craze, joking, "It would end my career. I'd be in prison after about two days. I mean, no, God almighty. Me and my big mouth, no thank you. That would be the end of the career."
