She knows how to hit the right note!Mariah Carey dazzles in a low-cut gown at the BET Honors.

The Diva Is Back! The I Will Always Love You singer's blonde tresses were gently curled and framed her beautifully made-up face.
Mariah Carey hit all the right notes in a very revealing black gown at the BET Honors at Warner Theatre in downtown Washington DC on Saturday evening.

The superstar singer slid her sexy body on to a piano to sing at the event, which fetes African Americans performing at top levels in music, literature, entertainment, education and more.But although the audience no doubt enjoyed her performance, it's likely that many viewers will have been wondering whether or not the 43-year-old's ample assets would remain inside the bodice of her dress.

The gown clung to her curves like a glove and displayed an eyeful of cleavage and side boob.
In fact, Mariah's outfit looked more than a little like the red dress worn by voluptuous cartoon character Jessica Rabbit in 1988 movie.

Hmmm Mariah.
