Los Angeles: Pop star Katy Perry finds her good friend Rihanna looking fresh and lively most of the time.
Perry, 28, says she wonders what is the secret behind the `Halo` hitmaker`s refreshing looks, reported Ace Showbiz.
"I think that Rihanna always looks so fresh and I`m like, `How do you do that? We all know how much pot you smoke! And you don`t sleep because you are on Instagram at four o`clock in the morning!" Perry said.
The singer had previously revealed that she meditates every day to prepare herself for work.
Perry also thinks 28 is the age to let go of childish things.
"I am 28, and... When you are at the end of your 20s, it is a very important growing time. I think that it is a very important time, when you kind of let go of childish things and accept the wisdom that comes with age. That is exactly where I am now," she said.
