Beatles legend John Lennon was a secret womaniser who even cheated during his "lost weekend" with former assistant MAY PANG. Lennon and Pang dated for 18 months after the rocker's wife Yoko Ono set them up - in a bizarre attempt to save her faltering marriage. The couple spent time in New York and Los Angeles during their relationship - where she caught him cheating twice. She says, "I know he had a couple of affairs. But he would come back. And when I found out, he'd say, 'I'm sorry.' "And I forgave him. It was his insecurity. He was like, 'I'm with somebody, am I making the right decisions?' and he did something stupid, and he came back. "It was just one-night-stands. He had one in New York and one in L.A. I forgave him. Absolutely. It was one night. What was I going to do? It wasn't something that carried on over and over and over again." Pang, 57, is currently promoting a book of rare Lennon photographs, Instamatic Karma.
