Rihanna made an AWW-worthy instagram collage in honor of Katy Perry's birthday!

Rihanna made Katy Perry an Instagram photo collage for her 29th birthday!

It’s official: When she’s not busy upside-down twerking over a pool in Greece, Rihanna is toooootally putzing around on Instagram just like the rest of us!

Which brings us to Ri’s latest arts & crafts experiment: a heartwarming, “AWW”-inducing Insta-collage for bestie Katy Perry‘s 29th birthday! Or, in simpler terms: nine adorable photos of Ri and Katy BFF-ing the eff out.

Along with the “Brady Bunch”-style photo grid, Rihanna captioned: “Happy Birthday to my lover and friend !! I miss you so much!! I love the phuck outta you!! I hope I could squeeze on you soon!! #KatyAnna @katyperry.”

All together now: AWWWWWW. Also: This isn’t your typical celebrity friend-a-thon! This Insta-collage is just the cherry atop a years-long, thigh-slapping friendship. Take it away, ladies:

Rihanna and Katy Perry doing the BFF leg slap!

KatyAnna totally coined the BFF “leg slap.”

But things weren’t always so rosy in between Rihanna and Katy (which is why we’re even happier to see the above collage). Presumably because Katy disapproved of Rihanna’s relationship with Chris Brown, the onetime 2012 MTV VMA BFFAEswannabe collaboratorsfriends with (platonic) benefits, and Coachella attendees took a brief friendship hiatus last year.

Then, in mid-August of this year, all Instagram evidence pointed to a happy reconciliation when Ri attended the “Roar” singer’s pre-Prism release party! And now the Insta-collage? If that’s not perma-BFF status, we’re not sure what is.
