Pop beauty Katy Perry has teased her 35.9 million Twitter followers today (May 2) by confirming that she will make an 'exciting' announcement later on.

Writing on her social networking page earlier this afternoon, the 'Teenage Dream' superstar told fans to keep an eye out for the news:

"I have something very exciting to reveal to you later today... Stay tuned!!!"

Perry has been working in the studio on her forthcoming new album and recently explained that she has teamed up with the likes of Bonnie McKee, Dr. Luke, Max Martin and Greg Kurstin for the offering:

"It's like the dream team. They push me the most, and also argue the most. It's an emotional abuse session. I'm a student of life. Words are like little treasures. I put all of my ideas in a folder, whether I read them in newspaper or through a conversation with friends. I've got years of titles and things I want to write about."
