A brother and sister acrobatic roller skating team are pushing the boundaries for the judge cuts round of America’s Got Talent 2017. During Tuesday’s performance, Billy and Emily England perform a variety of fast spinning moves with Billy twirling his sister around a small, round flat surface. For their last trick of the act, Billy twirls Emily around while only holding onto her with one hand. Emily is holding onto Billy’s beard. “Bloody hell, guys,” said Simon Cowell as they finished. “We couldn’t rehearse it because he lost so much hair that we were scared it wouldn’t be possible,” said Emily. “Okay, well, I actually turned around with fear, but I looked to the audience and they– their jaws were just like, oh, my gosh. So I know what you did was really stupid and incredible,” said Mel B. “It’s the best act of the day,” said Heidi Klum. “Hands down.” “For me, you pushed the boundaries, and that’s what entertainers and stars do. This was unbelievable,” said Simon Cowell. “Actually at a different level to everything else so far. Thank you so much.” Billy and Emily were selected as one of the acts to go through to the live quarterfinal round. “Me and my brother have been roller skating since we were six years old,” Emily said during the audition round. “Our mom got us roller skates just to get us out of the house,” said Billy. “When it was raining, she used to take all the furniture out of the kitchen so we could use it as a skating rink.” Billy and Emily are originally from England, but now live in Las Vegas.
