Katy Perry and Rihanna are known BFF's. These two are usually inseparable at award shows and it may seem that Katy Perry may have revealed a little too much about her friend's choices.

The "Roar" singer was recently interviewed for Elle Canada where she spilled a little too much on her Barbadian friend, Rihanna. In her interview the singer had said:

'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!'

She had also gone to say the following:

"'And you don't sleep because you're on Instagram at four o'clock in the morning. I'll get her secret for you.'

Riri and Katy Perry have been friends for years after meeting in show business. The two have been spotted together, have sung each other's songs in their own concerts just to greet each other a happy birthday. The two have been pictured together, hugging and practically having fun with each other.

Recently, the two best friends have had a row about the man Rihanna was dating-Chris Brown.

Perry, who is 28, said that she is "done" with trying to stop and advice her friend from making the same old mistakes she does with men. The two have made up and are back to being best friends.

Perry's latest album, Prism, is her maturing in the music industry. She had also said:

"'I'm 28, and I don't know how young you are, but, as you must know, when you're at the end of your 20s, it's a very important growing time. It's called the Saturn return, if you like astrology - I know it's important for me. I make sure to give myself a break. I had to find that balance. 'But I learned this thing called Transcendental Meditation, which I do as much as I possibly can. It's 20 minutes and you're supposed to do it twice a day, but I only do it once every other day - but anyway, it works. People say you should work out 30 minutes a day-none of us works out 30 minutes a day!'
