Mariah Carey enlists R. Kelly to add vocals to “Betcha Gon’ Know,” a tune from her 2009 album, Memoirs of An Imperfect Angel.

As far as additions go, Kelly is a perfect choice as he adds a verse to make this version easily fit as a chapter in his Trapped in the Closet series with the conversational storyline of a cheating lover.

This version of “Betcha Gon’ Know” will grace Me. I Am Mariah…The Elusive Chanteuse dropping on May 27. Pre-order above.
