It all went down when Chrissy posted a video of herself getting down to Sia's "Chandelier" on Instagram. Hilariously and perfectly mocking Dance Moms star Maddie in the song's video, Chrissy busts out her moves and makes us chuckle.
We obviously weren't the only ones who saw the clip, because Selena shortly posted a video of her getting down to the song too. That's when she challenged Chrissy to a dance off.
We're thinking Selena called Chrissy out because they're known to wear the same dresses all of the time. Which sexy gal do you think busted out the best dance moves? Think you can groove better than them?
