Veteran actor Martin Sheen has such a bad memory, he once brushed off a meeting with singer Paula Abdul - after failing to recognise his former daughter-in-law.
The screen legend was at a fundraising gala several years ago when he was greeted by his son Emilio Estevez's ex-wife Abdul.
But Sheen had trouble recalling exactly where he knew the familiar face from, much to her disappointment.
He explains, "About 10 or 12 years ago I was at a fundraising event in Beverly Hills... and a very beautiful young woman appeared right here at my elbow and said, 'Hi Martin, how you doing?'
"I turned around and said, 'Hey, how you doing?' and I kept walking and she got in front of me and said, 'Martin, you don't remember me?!' and I was like, 'Look, I'm gonna be direct. I know I know you, but I'm afraid I don't know from where, so please just tell me.'
"And she said, 'I'm Paula Abdul.' She was married to one of my children! Naturally she was very upset but she's a very good sport about it!"
Abdul split from actor Estevez in 1994 after two years of marriage.
