Beyonce Knowles In Vrettos Vrettakos Couture - Brit Awards 2014

Beyonce Knowles was the surprise performer at the Brit Awards 2014 held at the O2 Arena in London on Wednesday evening (February 19).

Showcasing her bootylicious bod, the singer turned to Greek designer, Vrettos Vrettakos, for her performance look.

Bey looked absolutely sensational wearing sparkling green form-fitting, long-sleeved frock featuring sheer panels in the sleeves while performing her new song, ‘XO,’ for the first time during a televised performance.

Vrettos Vrettakos is the same designer who made that stunning blue catsuit she wore on her ‘Mrs Carter’ World Tour.

Lorraine Schwartz jewels accessorized her look.
