She is one of the hottest singers in Hollywood.
And Katy Perry sent temperatures soaring as she worked a skintight leather red dress for Instagram followers on Sunday.
The I Kissed A Girl songstress, 36, shared snaps of herself posing in between American Idol takes, where she looked ravishing in the crimson frock with thigh-high PVC boots.
The plunging number clung to Katy's wait and flashed a hint of leg as she posed for the camera with her hands upon her svelte torso.
The Roar singer looked fierce with her blonde hair styled into a sleek 'do that framed her exquisitely done makeup.
Long full lashes brought out her blue eyes while a tint of lipstick added to the red hot vibe.

'ARE YOU WATCHING THIS RED HOT DRAMA?! DONT FORGET TO VOTE... 4 BECOME 3 TONIGHT #AMERICANIDOL,' Katy captioned the snap, along with a couple of flame emojis.

The stakes were high on Sunday's episode of American Idol, but Katy still managed to inject a bit of humor as she judged the crop of contestants.

She'd just watched 21-year-old caretaker Willie Spence sing an original song called Never Be Alone, then do a soaring version of Beyoncé's I Was Here to great applause.
'Every time, I get chills,' marveled Katy, 36. 'Tonight, I got chills on places on my face that I thought I had frozen. Okay? You brought the chills back. It was a Lazarus moment on my face.'
'You have that connection to the next realm,' she told the Douglas, Georgia, resident. 'And it's been so beautiful to see you come in-kind of shy, with this big voice, not so sure-and you are stepping into your power and you are walking in the light.'
Sunday's show found the Top Four singers debuting their first singles, performing a song made famous by a personal idol, and revisiting a past performance.
