Have Rihanna and Katy Perry put their differences aside? 

The two had been rumored to be feuding because Katy Perry reportedly didn't approve of Rihanna dating Chris Brown, but they don't seem to be feuding at the moment.

Katy put those ugly rumors to rest with a cheery birthday message to RiRi on February 20: 

Yay! We love it when our favorite pop stars on getting along!

So they might not be besties, but it's nice to see that Katy is wishing Rihanna the best. Mai Tais all around!
