Singer Beyonce Knowles suffered an embarrassing wardrobe malfunction when her blouse burst open during a performance here.

The singer's lacy white blouse popped open revealing her flesh coloured brassiere mid-way through the performance at the Great Lawn of Central Park. However, the `Crazy in love` hitmaker was unruffled by the mishap and continued with her performance in front of 60,000 people.

The singer was performing with her husband and rapper Jay-Z in Global Citizen Festival Saturday when the mishap happened, reports dailymail.co.uk.

Her appearance came as a surprise to the audience who had only been expecting to see Jay Z.
