Katy Perry on 'American Idol.'

Katy Perry dressed the part for Disney Night on American Idol.

With just weeks to go until the season 19 winner of Idol is crowned, the contestants and judges headed to Walt Disney World to perform songs from the Disney songbook for Sunday night's (May 2) episode.

Perry previewed the night ahead on social media with a first look at turning into a Disney icon, Tinker Bell.

"legolas’s gf flyin in hot with a pouch full of pixie dust to throw on anyone who doesn’t believe we have the best top 10 in @americanidol history #disneynight ok," she tweeted alongside a video of her ear transformation.

While Idol aired, Luke Bryan shared a clip on Twitter of Perry in full pixie dust mode.

"Katy goes all out," he commented, to which she replied, "Why would I go halfway? That's for losers."
