VIDEO : Ariana Grande Adorably Pokes Fun at Boyfriend Mac Miller's Hat on Instagram

Ariana Grande may love Mac Miller, but she doesn't feel the same way about his hat. Grande wrote alongside the snap of Miller rocking some unique headwear. "When you're about to have a week off and that hasn't happened in a long a** time so you finally wear that hat you've been wondering when you'd wear forever ?," the couple has been dating since September and Miller just finished the last show of his Divine Feminine Tour.
