Amanda Holden has sparked further complaints as she wore a revealing dress on Britain's Got Talent.The 49 year old, who recently channeled her inner woman boss as she stunned in a blue co-ord, appeared on the semi-final of the show this evening in a gorgeous dark purple gown.The floor-length number featured one long sleeve and a corset bodice alongside a thigh-high split, allowing the star to flash her toned and tanned legs for all to see.
