Katy Perry’s new album, Teenage Dream is dropping in stores on August 24. “It’s taking up way more time than my tour” Rihanna laughed to Access. “It’s so much pressure. Her wedding is probably going to be the best wedding I’ll ever go to and now I have to match the bachelorette party to that.”

Perry talks in-depth about a handful of songs on the album, including “Circle the Drain,” which Billboard’s Monica Herrera writes is “about ex-boyfriend, Gym Class Heroes frontman Travie McCoy,” and features the lyrics “You fall asleep during foreplay/ ‘Cause the pills you take, I know your forte/ I’m not sticking around to watch you go down.”

She also claims that making much of Teenage Dream was a battle of wills with her all-star team of producers, one that she was determined not to lose, no matter the cost.
