If anyone knows how to take a theme to 100, it's Katy Perry! And she certainly pulled out all the stops for her first season as a judge on the new ABC iteration of American Idol. Click through the gallery to see all of her looks from her competition show debut.
The 33-year-old singer swapped into a black rhinestone suit by Christian Siriano and black ITEM m6 bodysuit to perform "Part of Me" onstage with previously eliminated contestant Catie Turner during the American Idol finale.
Katy donned a long-sleeved, black full-length dress with ruffled purple tulle along the neckline and wrists that added major party flair for the competition show's finale.
Palm Springs Stunner
For the performance finals, the blonde bombshell looked ready to party in Palm Springs in a very '60s-esque feathered-and-beaded duster, baby blue blouse and matching wide-leg pants, which she paired with a winged bob.
For Idol's Mother's Day episode, Katy gave off major Cher vibes in this vintage-inspired multi-colored sequin halter dress with cold shoulders and diamond cut-outs along the waist, which she paired with Sara Weinstock cushion drop earrings and a white-gold EFFY Jewelry diamond ring. She finished off her look with a black center-part wig, bronze eyeshadow and a pink lip.
It's only appropriate that just days ahead of Met Gala 2018, the 33-year-old singer donned this very crimson sweetheart column dress with an angelic tulle shoulder-and-cape embellishment for the Top 7 ep, which honored Prince.
Fairest of Them All
No one does a theme better than Katy, which is why it was just too perfect that she turned up for Disney Night in a Snow White costume. The Top 10 episode was appropriately filmed at the happiest place on Earth, the Disneyland resort in Anaheim, California.
Pretty in Pink
The California girl looked pretty in pale pink sequins during the Top 10 reveal episode.
Sequins are the name of her game, which made this rainbow striped mini wrap dress the perfect look while narrowing the contestants down to just 14. She paired the fun frock with long gold chain earrings and a magenta lip.
Flanked by her fellow Idol judges, Luke Bryan and Lionel Richie, during a round of auditions, Katy opted for a pink metallic blazer, two-toned, shiny striped dress and silver circular earrings.
Can you tell she likes pink and sparkles? The "Swish Swish" singer was revved up for auditions in this one-shouldered, pastel sequined mini.
Birds of a Feather
Katy threw beads to revelers along Bourbon Street in New Orleans while wearing this pastel feather frock, and we are here for it! She accessorized a wide silver belt to cinch in her waist and sunglasses.
While in Nashville for auditions, the singer was thrown a puppy-themed early birthday party, which was just as sweet as her bedazzled black dress-and-vest ensemble.
