Jon Bon Jovi is amazed he counts Sir Paul McCartney as a close friend

Speaking to AARP - The magazine, Jon showed off a photo of himself and Paul chatting at a picnic table in the grounds of his home in the Hamptons and said with disbelief: "We do this all summer. I'm sitting there with a f****** Beatle. He comes to my house often, I go to his beach house often, and our wives are very close."

Jon added he's most impressed by how Sir Paul is still enthusiastic about making music in his 80s.

He said: "(He goes), 'Oh, I've got new stuff!' At 81. Crazy."

But Jon himself may keep working for just as long as he thinks he is only getting better as a songwriter as he gets older.

He said: "I have a grander palette to write from. More life experience. I think that every record reflects somehow who I am at that time."

The 'Always' hitmaker has no desire to write the way he used to.

He said: "'Don't try to be what you used to be.' I don't want to be the kid from 'Slippery When Wet'. I have no desire to be that kid."

Jon is still recovering from vocal surgery and though he doesn't know if he'll ever be able to handle a lengthy tour again, he's looking forward to getting back out on stage and having a good time.

He said: "Whether or not I can ever do a 100-show tour again, I don't know.

"But if I can have joy on the stage on night one, that would be great."
