Katy Perry is clearly in awe of Rihanna.

But while chatting to Elle Canada, the "Roar" songstress may have revealed too much about her pal. Or did she?

"I think Rihanna always looks so fresh and I'm like, 'How do you do that? We all know how much pot you smoke!'" Perry tells the magazine in its October issue. "And you don't sleep because you're on Instagram at 4 o'clock in the morning!"

Of course, there certainly seems to be some truth to the latter as the Barbadian beauty does have quite a fondness for posting pics.

As for Perry's other claim that her friend likes to light up?

Well, Rihanna did Instagram a photo back in April of a cake that a fan made in the shape of a marijuana leaf, and in June, she took to Instagram again to show off what appeared to be two giant joints in Amsterdam.

But we'll just leave it at that. After all, Perry could have simply been joking. Or not.
