As a pop mega-star, Beyoncé must surely be used to designer clothes and yet she happily partied the night away wearing a £20 T-shirt from high street favourite New Look.Following a show at London's O2 arena, Beyoncé decided to celebrate at Mahiki with hubby Jay-Z and Rihanna but was obviously tired of all the big name labels.

Instead she opted for the low cost Idol Batwing top from New Look, giving it her own style by buying a bigger size to create a T-shirt mini-dress.

And Ms Knowles is no stranger to high street fashion.

Earlier in the week, she stepped out in a striped dress from Reiss, along with a military jacket from the same store, while on a recent trip to South Korea the singer was snapped sporting a Topshop trophy jacket.

Absolutely fabulous she may be, but Beyoncé clearly has an eye for a bargain.
