All has been quiet on the Katy Perry music front lately, but it appears that something has been brewing in the "Dark Horse" singer's lab of late. As to be expected with any large pop star, there have been rumors and plenty of speculation from die-hard fans, but nothing concrete as of yet. That seems to have changed. According to the résumé of decorated mixer Serban Ghenea via Popjustice, there are three new Katy Perry songs that he has worked on, titled "She's So Creepy," "In Flames" and "Heartache Crusade."

Check out his résumé in the document here and skip to Page 4 of 23 to see the evidence. Ghenea has mixed for artists like Keith Urban, Miley Cyrus, Justin Bieber, Kesha, One Direction, Rihanna, Usher, Katy Perry and more. He has worked on just about every big pop star of the past 15 years in music.

The song "She's So Creepy" could be throwing shade at Taylor Swift and would bring their public tiff to a new level from the occasional comment and social media jab into discographies. Katy Petty would be pulling a Taylor Swift by writing a song about an enemy. The irony.

Perry fans are waiting for the follow-up to her 2013 album Prism, which produced hits like "Roar" and "Dark Horse" and dominated the pop landscape for months. Katy Perry is still touring in support of Prism, so do not expect much in the way of an album anytime soon, but this news suggests that there is something in the works. She has potentially her biggest show ever in one month: her halftime performance during the Super Bowl Feb. 1. She could use the opportunity to premiere some new material, though the NFL prefers something safe after Janet Jackson's PR boon fiasco.

None of this has been confirmed by the Perry camp, but we will let you know if there is any world from them.
