R&B stars Alicia Keys and Maxwell are reuniting in the studio for a new duets album.

The Empire State of Mind hitmaker invited Maxwell to join her on the ballad Fire We Make for her latest album, Girl on Fire, and it appears their musical chemistry has inspired the singers to record a whole project together.

Maxwell tells Billboard.com, "We got a thing musically. That's like my little sister. What's funny is Swizz (Beatz, Keys' husband) is the champion of all of it... She's someone that I trust... And I'm proud to say that I've known them 20 years almost."
