Little Mix's Leigh-Anne Pinnock thinks Prince Harry is called Barry

Leigh-Anne Pinnock has no idea who Prince Harry is.

Since her X Factor win as one-quarter of Little Mix, Leigh-Anne has been hitting popular celebrity club Mahiki - a favourite with

Wills' little brother.

'We had our own VIP room section,' says Leigh-Anne, 19.

'We had like a bed in it and a shower, it was just crazy but I think it's the same room that Prince Barry or someone had, is it

Prince Barry?

'Who's the one that goes clubbing?'

Though Leigh-Anne's not familiar with the handsome Prince, she's more clued up about top US singers - like Rihanna, who performed

on last year's series of The X Factor.

'She walked past, did a double take and said, "Your hair is awesome",' Leigh-Anne tells The Mirror.

'I just froze. I couldn't believe she noticed me.'
