Grande, who collaborates with Iggy Azalea in the original song, has reacted to the cover on Twitter and praises the a capella group for the new version.
Pentatonix is back with a new cover and proves there's nothing they can't sing. The group shared a video of them performing an a capella rendition of Ariana Grande's summer jam "Problem" on Tuesday, August 12.
The five-piece performs 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.
"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 and she has nothing but nice words about it. "Omg y'all. my favs. been waiting! better SING i love u," she wrote.
Pentatonix is currently working on two projects that they plan to release this fall. Earlier this month, they announced their new EP called "PTX, Vol. III" would hit the stores on September 23. Marking their first set to be released via RCA Records, it will again 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.
