Mac MIller's family recently released his posthumous album, Circles, and fans are absolutely loving it.
There's one official feature on the album, with Melbourne artist Baro Sura credited as playing drums and singing on Hand Me Downs, but fans have noticed another feature on the album's fifth track, I Can See.

Ariana Grande appears to have contributed backing vocals to the song, but wasn't credited - not that that stopped fans picking up on the feature. After all, Ari's vocals are very distinctive.
To add to the speculation, just two days before the album was released, Ariana tweeted "i love adding more harmonies than anyone will ever notice or hear that no one ever asked for or needed."

“I Can See” is my new favorite song by Mac Miller from #Circles
And I’m not 100% sure if it’s her, but it sounds like Ariana Grande has some vocals in the background harmonies. It sounds amazing.— Tony Pajamas (@dinixluna) January 17, 2020
We're hoping Ariana confirms she was featured on the album - but until then, we're pretty confident this is her. Have a listen for yourself and see if you can pick it.
