McCartney Unmasked!

Paul’s good-guy image hiding hooker passion, Michael Jackson grudge & truth about Beatles’ end

AILING music legend Paul McCartney is revealing his shocking secret life — including the truth about the Beatles’ breakup and his rock ’n’ roll sex life — in a no-holds barred attempt to set the record straight before he dies, sources tell GLOBE!

In frank and candid conversations, the 76-year-old star — who’s said to being suffering from the early stages of Alzheimer’s — is stripping away his wholesome image by dropping bombshell revelations about cheating, boozing and domestic abuse, insiders dish.

Despite critical acclaim and a new concert tour, “Paul grumbles he’s just another washedup old guy in the music biz now, so why not reveal his true feelings,” snitches a source who fears the Band on the Run singer has become forgetful and wants to make sure his memory is clear as he tells all.

“There’s a chance he’s got Alzheimer’s,” says the source. “He barely remembers the lyrics to his songs — and takes this as a sign that the clock is ticking on his time on Earth.”

Shockingly, Paul recently admitted he couldn’t remember how to sing a Beatles song anymore — and when he looked at a band picture, he didn’t even recognize his pal Ringo Starr!
