The Saturdays' Vanessa White has apologised for the gaffe

Vanessa White accidentally exposed her breasts at Jay-Z's Brit Awards after-party.

The Saturdays singer wore a see-through outfit to the bash at London's Merah club.

When the camera flashes went off, it was clear Vanessa wasn't wearing a bra. 

'Oh God, I've seen pictures,' the 20-year-old tells The Sun. 'I am mortified!

'I didn't realise how see through it was when I got dressed.

'I'm sorry if I offended anyone. No one wants to see that.'
