Watch Cimorelli Cover Demi Lovato’s ‘Heart Attack’ (VIDEO)

Watch Cimorelli, aka SIX SINGING SISTERS, cover Demi Lovato’s “Heart Attack.”

I’m an only child, so the thought of having SIX siblings — let alone SISTERS — is quite frankly scary as hell. That said, if I did have six sisters, I’d probably spend most of my time being jealous of their clothes, as opposed to FORMING A TOTALLY SUCCESSFUL BAND like the all-sister group Cimorelli. Yep, Cimorelli is six pop music-loving sisters — Christina, Katherine, Lisa, Amy, Lauren, and Dani Cimorelli — who went viral on YouTube covering songs like Taylor Swift’s “22” and One Direction’s “What Makes You Beautiful.” And now that we’ve given them a proper intro, check out Cimorelli’s latest cover of Demi Lovato’s “Heart Attack“!

Armed with only their voices and an acoustic guitar, Cimorelli give “Heart Attack” the a cappella treatment, swapping the the original production for a stripped-down, organic version complete with six-part harmonies. And sure, we know that “a cappella” anything tends to get a dorky reputation, but worry not — Cimorelli comes with a TON of cred. In just two days, their “Heart Attack” video got nearly 500K plays on YouTube and even earned a global hashtag on Twitter, “#CimorelliHeartAttackTonight.” Yeah, calling up my three girl cousins THIS INSTANT to ask if they wanna get together for a “jam sesh” later.
