Kirstin Maldonado is K-poppin’ it like it’s hot…

The 29-year-old half-Mexican, part-Spanish American singer and her Pentatonix group mates have released a mash-up of two Billboard Hot 100 No. 1 hits from BTS.

Cutting into the group’s rendition of Jung Kook‘s hook on “Dynamite,” Scott Hoying slides in like a “criminal undercover” with the first verse of “Butter.”

Pentatonix’s colorful jackets and suspended newspaper props had a more serious air once the video turned black-and-white, like the official “Butter” music video. But don’t get it twisted: Hoying led the group into a groove that was anything but serious.

Eventually Matt Sallee and Mitch Grassi took the lead when the two got back into Pentatonix’s technicolor “Dynamite” performance before switching back to black-and-white with the group’s airy “Dyn-na-na-na, na-na, na-na, ayy” harmonies smoothly flowing into “Get it, let it roll!”

In late July, Pentatonix asked their Twitter fans in a poll which BTS song they should cover between “Butter” and “Dynamite,” and even though the former single took the lead, the quintet decided why not just go for both?
