Perry showed up for the "American Idol" season 21 finale looking glamorous in an orange outfit made by fashion designer Giuseppe Di Morabito.

The dress, which showed off her toned midriff, was designed with shiny stones closely packed across its entire surface.

Its top part featured multiple cutouts and flower-like accouterments, giving it an exquisite look. Down below, the racy, high waist see-through skirt hugged tightly to Perry's figure and trailed with a tail that swept the floor.

The singer also wore briefs that covered her privates and matched the color of the racy fashion piece.

Perry put on diamond stud earrings and her oval-cut ruby engagement ring from her fiance Orlando Bloom for her accessories.

Her baby pink manicured nails were short and natural-looking, and she let her lengthy raven locks down with one side cascading over her in waves.

Following the finale, in which singer Ian Tongi took home the ultimate prize, Perry took to Instagram to share pictures of her sexy look with the caption, "Orange you glad it was a great #idolfinale?

The pictures have since garnered over 100,000 likes after Perry uploaded them on her page as fans were star-struck with the singer's beauty.

The comment section also sizzled with cute comments and several heart emojis that further appreciated Perry's fit body.

One fan commented, "Serve after serve after serve. They just keep coming," while another one penned, "Wow, what a gorgeous dress you have on Katy Perry. Your beautiful."

The singer's fiance also showed up in the comment section twice, dropping a flame emoji the first time and returning to share a peach emoji.

Katy joined "American Idol" as a judge in 2018 during season 16, which marked the first time the show aired on ABC after over 15 years on Fox.

However, earlier in the month, she recently faced backlash for her seemingly harsh comments as a judge on the show while she was away performing at the coronation of British monarch King Charles.

At the time, she was temporarily replaced by Morissette, whom fans say should take over from Perry for the next season.

One fan commented, "Your comments were unselfishly intended to benefit the contestants, unlike those of other judges @LionelRichie & @katyperry could certainly take a lesson from you."

Another fan said, "You are, and we're soo awesome on A. I., Not that I don't like Katie. But if she quits, I wish you would be the next judge. Your music was strong for me back then as it is now."

For the past coronation, Perry joined other A-listers such as Dame Judi Dench, Emma Thompson, and her "American Idol" co-star, Lionel Richie, to celebrate Charles' ascent to the throne.

She and the others performed in front of over 20,000 guests, thrilling them with several classic songs.

After the performance, the singer's beau praised her in a sweet Instagram post.

He wrote the caption, "Immensely proud of you, my love. You always bring the light," on a picture of an army of drones forming a shiny lion's head above the stage during Katy's rendition of "Roar."
