Kelly Clarkson is in good company backstage at the Grammys.

The original "American Idol" champion, who's performing at Sunday's ceremony, posted a photo to Instagram of her dressing room door, which featured the names of her roommates: Alicia Keys and Miranda Lambert.

"Our dressing room rules!" wrote the "Stronger" singer.

Clarkson later uploaded photos of her glam squad curling her hair, as well as a close-up of her glittery custom nail polish.

"Should we call it 'Stronger'?" she asked.
