Rihanna and Katy Perry dance in the audience during Coachella.

Since we weren't there, it's been killing us to experience Coachella vicariously through all the pics currently dominating the Internet. But we weren't prepared for this sucker punch. Basically, we missed the most amazing moment ever created in music history (aside from the mind-blowing Tupac resurrection): a dance party with Rihanna and Katy Perry!

We already knew that the two gorg singers were BFFs, but this photo pretty much proves that the ladies know how to have a realllly good time when they're together. Rihanna and Katy (sporting her new purple hair) spent the entire weekend rocking out to acts at the festival, and Ri brought down the house during her impromptu performance of "We Found Love" and "Where Have You Been" with Calvin Harris.

To reiterate what the majority of us have missed this past weekend: A rapper was brought back to life AND tons of Katy/Rihanna spottings. I'm depressed.
