This past week on 'America's Got Talent The Champions' one of the international champions was a dude who sang a male female duet and pulled it off perfectly. It's a pretty cool that he can do that and that got some cast members wondering if they could do the same. Some cast members put more effort into this bit than others and we'll let you guess who did what!

Ok, it's no surprise that Kellie nailed it, but what about J-Si, Jenna and Big Al?
