The singers cover a classic.
Tinashe takes on an old Mariah track.
While fans wait patiently for her new album, Tinashe has teamed up with DJ Cassidy for new song 'Genius Of Love'.
You may recognise the 'Tom Tom Club' sample from Mariah Carey's 1995 track 'Fantasy' with Old Dirty B**stard.
The 80's sample has also been used by Grandmaster Flash and the Furious Five, Public Enemy, Redman, Cam'ron in the past.
The track will be the soundtrack for American brand Target's Spring style ad campaign called 'Around Town'.
Meanwhile, Tinashe's 'Joyride' tour named after the upcoming album, kicks off at the end of February.
There is currently no release date for the project.
