Have you heard of the hot YouTube act Cimorelli? The band is made up of sisters Christina, Katherine, Lisa, Amy, Lauren, and Dani and they were recently signed to Universal Music’s Island label. Just because their career is moving beyond YouTube though, doesn’t mean the girls have forgotten their roots. They still post awesome cover videos on YouTube for their loyal fans and this week, they gave us a cover of Justin Bieber and Nicki Minaj‘s hit, “Beauty and a Beat.” Check out the video and tell us what you think of Cimorelli in the comments!
