Have you seen pop singer's Alexandra Burke latest fashion unflattering appearance? While taking the stage at Royal Albert Hall on Sunday night, May 28 to perform along Dionne Warwick at the World Hunger Day concert.

The 23-year-old singer joined th charity gig, but her fashion style was inappropriate for such event. Alexandra hit the stage in a much revealing lace top, sans bra leaving too much to the imagination.

Before the performance, Alexandra wrote on her Twitter page: "About to perform with Dionne Warwick... So nervous x". She later added: "Show done.. I can't believe my luck. I actually got to sing with Dionne Warwick. I'm still speechless."
