Kelly Rowland once went on a double date with Beyonce Knowles - but was so tired she fell asleep.

The Destiny's Child star had had a tiring day when she went out for the night - and all didn't go as planned.

She tells British magazine Closer, "I once fell asleep while on a double date with Beyonce.

"I'd been working so hard and we'd gone to see There's Something About Mary at the cinema.

"The lights went up and I was actually slobbering on the guy's shoulder. It was terrible."
