HIGH ON DRUGS???? R&B SINGER KEYSHIA COLE RELEASES A VIDEO . . . OF HER HUMPING THE PIANO . . . LIKE SHE WAS A DOG IN HEAT!!!

Keyshia was looking kinda FRANKIE-ISH in this video she uploaded onto Facebook. She posted this
video on Instagram - then tagged her boyfriend BIRDMAN. She's since deleted the video off Instagram . . . but it's still up on Facebook.

We hope everything is alright with her. :(
