Star Spotting: Rihanna And Katy Perry Are Back On The BFF Train! (PHOTO)

Katy Perry and Rihanna are reunited, and it feels so good!

KatyAnna is BACK, y'all.

It looks like Katy Perry and Rihanna have both purchased a one-way train ticket to bestie-land, and said train is CRUISING. In case you forgot, Rihanna and Katy Perry used to be, like, Selena Gomez and Demi Lovato levels of BFF status before Sel bestie'd up with Taylor Swift. In other words, KatyAnna were 2012 MTV VMA BFFAE, wannabe collaborators, friends with (platonic) benefits, co-Coachella attendees, and an all-around attractive friend pairing. Then, presumably because Katy disapproved of Rihanna reconnecting with Chris Brown, the two gals took a break. UNTIL NOW!

Rihanna Instagrammed the above shot of herself and Katy at the "Roar" singer's pre-Prism release party, along with the caption: "She. X She. #KatyAnna #RIHunited." And there you have it, folks! A confirmed RIHunion for the ages! Rihanna's reconciliation with the 2013 VMA performer comes on the heels of Katy's revealing Elle UK interview, where she indirectly named Rihanna's entourage as the source of strain in their relationship: "I love her [Rihanna] and every time I see her, I'm reminded of the light that she has... I know a lot of people out there with the most detrimental entourages -- they are the root of their demise." True, but we can see the friendship light shining bright like a diamond between you two, so we say keep it up. Here's to many more adorable BFF4LYFE-style Instagrams in the future!
