The first single off of Katy Perry's upcoming album, Prism, has leaked.

According to DailyNews, "Roar," the singer's first single for her fourth studio album, was originally scheduled to release on Aug. 12, but leaked a few days early. Perry, 28, responded on Twitter to the early release by saying, "Looks like there's a tiger on the loose!!!"

ContactMusic describes the track as upbeat but lacking Perry's signature bright and cheerful pop sound. The message for "Roar" is similar to other inspirational Katy Perry anthems like "Firework" and "Wide Awake." The chorus declares the powerful message, "I got the eye of the tiger, the fire/Dancing through the fire, 'cause I am a champion/ And you're gonna hear me roar." The single is sure to dominate radiowaves in the upcoming weeks and top ITunes charts when it is available for download by Monday night.

LATimes reports that promo clips for the album’s lead single was making rounds on the internet, creating hype for the song. In the promo, Perry burns her signature blue wig as a way to end her sweet and sugar coated image.

Give her new song a listen below.

Prism is due out Oct. 22.
