Diana Vickers & Pixie Lott flashed their “Underwear” accidentally on stage in Wales

She turns 21 on Monday and Diana Vickers was eager to prove she’s all grown up as she flashed her underwear on stage in Wales yesterday. 

The former X Factor contestant performed among a line-up which included Olly Murs, Pixie Lott and Cover Drive at the Access All Eirias concert in Colwyn Bay but she made sure all eyes were on her in a daring outfit.

The blonde singer wore a purple T-shirt embellished with silver tassels for her turn on the main stage but appeared to have forgotten the rest of her outfit as she paired it with just a pair of printed underwear and matching heels.
