The duo's crazyness isn't just confined to red carpets anymore. They Instagrammed their own little, hilarious impromptu versions of Taylor's "Trouble" and Miley's "Party in the U.S.A" and had us cracking up.
Hot Pursuit hits theaters on May 8. If that's as funny as these two clips, it's going to be a smash!
Watch the ladies take on Tay and Miley, below. We dare you not to laugh!
