and Alesha Dixon
went head-to-head in the style stakes
on Britain's Got Talent
on Monday night.
The female judges pulled out all the stops for the first live show
. Amanda was stunning in a white, floor-length caped gown, while Alesha kept it short and sweet in a metallic gold minidress with a fitted bodice and embellished waist.
