Sheryl Crow once had an embarrassing case of mistaken identity when a crowd of Las Vegas, Nevada revellers were convinced she was former Hollywood Madam Heidi Fleiss.

The singer felt sure she'd been recognised for the first time at the beginning of her career - but the lads thought she was a hooker.

She tells Blender magazine, "My first record had just broken and these guys wanted my autograph. I thought, `Oh God, they recognise me!'

"Turns out they thought I was Heidi Fleiss."
