Moore, who wore a black mini dress with a revealing open back, was initially sitting along with her husband before she decided to join the singer on stage. Once she was on stage, she started shaking a leg, and even tried to persuade Kutcher to join them.
Following the impromptu stage performance, Moore posted her picture along with her husband on her Twitter page. With the picture, she posted – “Boy do we look smart!”.
The duo, who married in 2005, were seen posing in a booth, wearing matching black-framed glasses.
