"Betcha Gon' Know (The Prologue)" is a song by American singer and songwriter Mariah Carey, from her twelfth studio album Memoirs of an Imperfect Angel (2009). It was co-written and co-produced by Carey, Christopher "Tricky" Stewart, James "Big Jim" Wright and The-Dream. The song was recorded at several recording locations, including The Boom Boom Room in Burbank, California, the Studio at the Palms in Las Vegas, Nevada and at Honeywest Studios in New York City. The lyrics revolve around the idea of outing a cheating boyfriend publicly on television, and Carey makes a reference to Oprah Winfrey and her chat show.
