Heather Rae El Moussa and Christina Haack have the BEST response to all their haters! The HGTV stars took to Instagram on Monday to clap back at those who say that "the world doesn't revolve around them." In the video, Christina and Heather stood back-to-back while passing the phone around to each other in a circle and giving the camera their best smiles. They then repeated it one more time before the Christina on the Coast star took it back and stuck her tongue out at the camera. All while Daft Punk's Around the World plays in the background.
