Tamar Braxton can sang! And on her Instagram, the star tagged several high profile celebrities in a singing challenge.

Tamar belted out the classic song "He's Got the Whole World in His Hands," in a video posted to social media. She captioned the post: 

"Even when we don’t have ourselves, My Dear God, You are the ONLY thing that has got us. We are depending on you. YOU are the only one who can fix this. This here is bigger than all of us......BUT you are BIGGER 🙏🏼 #HesGottheWholeWorldChallenge #GodBless #SingForHim," she wrote.

"With love tagging @adriennebailon, @majorgirl, @tiwasavage, @mariahcarey & @tonibraxton to join this challenge with me! ♥️"

The self-quarantine has got celebrities getting very creative with how they interact with their fans as well as each other. Now, we know that all of these ladies can belt out a decent tune -- but we wonder whether any of them will be brave enough to take up Tamar's challenge?
