The “Firework” singer shared a series of behind-the-scenes sexy shots from her newly released music video to “When I’m Gone.”

In the social media post, Perry posed with her arms up against the wall wearing nothing but a pair of black, wide-leg trousers — revealing some side boob.

In the following photos, the pop star, 37, took various selfies in front of a clothing rack, wearing outfits seen in the music video.

She captioned the Instagram post, “let it burn baby.”
