Pixie Lott reveals a little more than planned during a very cheeky performance at Michael Jackson tribute concert

She's renowned for her thigh-skimming dresses that often reveal plenty of leg, but Pixie Lott revealed a little more than normal during the Michael Jackson tribute concert this weekend.
The singer, 20, took to the stage in an ultra-short silver dress that threatened to ride up and expose a lot more flesh than both Pixie and her audience anticipated.
And, during her energetic performance it did exactly that - flashing her backside to the assembled Jacko fans at the Millennium Stadium in Cardiff on Saturday night.
