A contestant on British Big Brother gave viewers more than they'd bargained for when her skin-tight denim dress gave way on live television this week.

Departing contestant Lateysha Grace was being interviewed on the BB spin-off show Big Brother Bit On The Side when host Rylan Clark praised her twerking abilities, as seen during her time in the house.

Asked to give an impromptu demonstration of her skills, Grace dutifully stood up, turning around and began shaking her booty. Within seconds, though, this happened:

Grace reacted with a mixture of horror and hysteria as she realised she'd just bared her bum on national television, moaning "Why is this happening to me?"


Host Clark busied himself trying to fix her dress, but could barely contain his glee at what had just happened.

"You've just made my day!" he laughed.
