Brandy has already been in the studio with Monica
Brandy and Monica are re-teaming for a new collaboration - 14 years after they topped the charts together.
The Nineties R&B star won a Grammy Award for their 1998 duet The Boy is Mine, which spent 13 weeks at the top of the U.S. Billboard Hot 100.
Now the pair are reuniting for a follow-up to the hit track - on Saturday, they met up in a Miami, Florida studio to work on a new song.
Brandy took to her Twitter page to share the news with fans, admitting her voice was not up to scratch during the recording session.
She wrote: "Wonderful night in the studio! I wasn't 100%, but I gave it my all and it turned out great! Just a little more raspy than normal... I love you so much Mo. Thank you!"
Monica also tweeted a photo of herself with Brandy, adding: "We have Both Been Blessed Beyond Measure..14years later... Love."
