Shawn Mendes and Miley Cyrus are reportedly working on a secret duet which they are believed to be performing at the Grammys on Sunday.
The 20-year-old Canadian pop star and the 'Nothing Breaks Like a Heart' hitmaker are both set to perform at the Grammys on February 10, and the latter got their fans guessing they could be singing a duet together at the ceremony, after Miley shared a picture of herself rehearsing in front of some of Shawn's instruments.
Now, TMZ reports that the pair are in fact working on a secret song together.
Eagle-eyed fans of Shawn - who is nominated for Pop Album of The Year for his self-titled third studio album and Song of The Year for hit single 'In My Blood' - noticed that his name was written on one of the guitars.
Miley, 26, had captioned the Instagram post: "Gram Gram rehearsals! Performing this Sunday at the @recordingacademy ! (sic)"
