Pic: Mariah Carey checks into the studio with Nas...

Mariah Carey & Nas on a brand new cut? Er, yes please!
It's been thirteen years since the pair collaborated on the 2000 remix of 'Thank God I Found You' featuring Joe.

MC recently attended Nasir's 40th birthday bash so it can be assumed this is when they decided to hook up again for MC's upcoming new album.

The pair recently clocked studio time alongside Jermaine Dupri.
