Katy Perry donned a slinky ensemble for sultry new snaps as she encouraged her followers to cast their votes on American Idol.

On Sunday, the 37-year-old American Idol judge shared photos in which she was seen flashing her toned abs in a bright orange silk crop top with a matching wrap skirt as she leaned against a wall.

‘ORANGE,’ the I Kissed A Girl hitmaker wrote in the caption, adding emojis of orange hearts.

She continued, ‘you glad it’s now YOUR turn to vote?

‘@americanidol is on tonight and it’s the first half of the top 24 from hawaii,’ she concluded with emojis of a thumbs up and a tropical flower.

Katy’s long-sleeved top featured pink and silver sequined flower detailing and was tied in a knot at her midriff.

The Hot N Cold songstress showcased her sculpted legs in the high-slit skirt.

The beauty wore her raven locks pulled back with a few loose strands framing her face and accessorized with pink heart hoop earrings.

The 13-time Grammy nominee sported a dramatic palette of makeup including a deep pink lipstick, long lashes, a rosy blush and shimmery pink and orange eyeshadow that was highlighted with electric pink streaks.

Katy and fellow judges Lionel Richie and Luke Bryan will appear on American Idol alongside host Ryan Seacrest for a two-night event in Hawaii tonight and Monday on ABC.

Last Monday, the pop star stunned in an ankle-length metallic dress, as she headed to judge the reality competition show in Los Angeles.

She sported a metallic croc-style dress with a strapless bust and hourglass fit, with Katy adding a pair of silver pointed toe, ankle wrap court heels.
