Rock legend Sir Paul McCartney and his wife Heather Mills have been rejected as potential contestants for the British version of television quiz Who Wants To Be A Millionaire?

The newly-weds were keen to make an appearance on the celebrity version of the show to raise money for Heather's landmine charity - but host Chris Tarrant didn't think they would be good enough.

The former beatle and his campaigner wife bumped into Tarrant recently at a showbiz gathering.

McCartney says, "Heather, in her keenness, said, 'We should come on the Celebrity Millionaire show. I know all the answers Paul doesn't know and he knows all the ones I don't know.'

"Chris said, 'No, you shouldn't come on. You'd be terrible.' It was hilarious because you'd expect him to be really keen."
