Brandy has big plans for her next single, “Put It Down,” a collaboration with a rapping R&B powerhouse she refuses to name. With her upcoming album Two Eleven possibly pushed back to a July release date, Brandy talked up her new song.

“The thing we are working out now is that the single has a feature,” she told TrueExclusives.com. “It’s both a rapper and singer.”

While she did not directly name Chris Brown as the featured artists, there were some clues suggesting that he may be the “rapper and singer.”

Aside from releasing a string of songs on which Brown has displayed his MCing chops, the two recently spent some time in the studio together.

“The session was amazing,” Brandy said. “To work with people that love you and your craft and what you do, it makes the song even better and the experience even better because you are working with people that you love.”

When asked to describe the single with the mysterious guest performer, she allowed that it is an “uptempo” track that is “very very different.”

Her label wanted to release the single ASAP, according to Brandy, but she said fans will have to wait two weeks from now to find out the identity of this mystery guest. [See interview below.]
