Singer Katy Perry admits that her beauty ritual lasts for about 90 minutes.
The 28-year-old loves beauty products and takes a lot of time to complete her beauty regimen.
"I'm a product w****. I have a regimen that spans an hour and a half, and nothing goes out of order," usmagazine.com quoted her as saying.
She even said that it could be difficult to follow the regimen while "sleeping over at a new boyfriend's house."
