Kirstie Maldonado has a series problem…

The half-Mexican American/part-Spanish artist and her fellow Pentatonix members have released a new cover, proving there’s really nothing the quintet can’t sing.

The a capella group, who won NBC‘s singing competition The Sing-Off in 2011, shared a video of them performing their rendition of Ariana Grande‘s summer jam “Problem.”

Maldonado and the gang perform every part of the hit track with Kevin Olusola showing off his impressive beat-boxing skill. Meanwhile, Mitch Grassi spits the verses originally performed by Iggy Azalea in the original.

“Problem” is the lead single off Grande’s upcoming sophomore album, My Everything. The 21-year-old singer has responded to Pentatonix’s cover on Twitter, saying”Omg y’all. my favs. been waiting! better SING i love u,” she wrote.

Pentatonix is currently working on two projects that the group plans to release this fall. Earlier this month, they announced their new EP called PTX, Vol. III will arrive in  stores on September 23, marking their first project to be released by RCA Records. It will feature covers of hits and original tracks.

The EP will be followed by their second holiday album, That’s Christmas to Me, which is coming out on October 21. It will include a combination of classic holiday tracks, modern favorites and a one-of-a-kind holiday mash-up.
