As living R&B vocalists go, few can rival the premium of Tamia and Deborah Cox.

So, imagine the slay of a collaboration?

The ladies lived up to expectation during a virtual sing-a-long designed to lift spirits during this testing time.

Together they belted out a full version of Whitney Houston and Cece Winans classic ‘Count On Me.’

The dynamic duo joined forces in response to Winans’ #CountOnMeChallenge, which was launched akin to Tyler Perry’s #HesGotTheWholeWorldChallenge.

Watch the seasoned divas take vocal flight, accompanied by Shep Crawford, after the jump…

Incredible! We have chills.
