The 26-year-old "Fireworks" singer shared a picture of her royal digits via Twitter. "In honor of the Royal Wedding, I present you... My royal NAILS! CONGRATS! Perry tweeted.
From the newlywed's engagement photo shot by renowned photographer Mario Testino to an image of young William being held by his mother, the late Princess Diana, Perry pays tribute to the couple in a creative way.
But this isn't the first time the raven-haired beauty has dressed up her digits. We've seen her paint on eye-catching hues like neon yellow before hitting the red carpet and pres-on spiky nail extensions for her "E.T." music video.
Whatever the occasion, Perry is sure to flash fun nail art.
