Rihanna & Katy Perry 'Make Out' Amid Leonardo DiCaprio & Chris Brown Birthday Love [PHOTO]: Steamy 'Lesbian' Instagram Kiss Infuriates Karrueche Tran?

Rihanna's Hollywood gal pal Katy Perry wished the Barbadian beauty a very happy birthday earlier this month. If only this hot-and-steamy kiss between the two pop sensations were actually real!

katyperry: "HBD to my flawless friend @badgalriri may I bestow this gift of beautiful fan art of us embracing in a passionate almost kiss. I hope you go to bed with all your makeup on tonight aka black out. Luh you, miss you, hope to share a yacht with you in the future bb."

Better keep an eye on your girl, John Mayer!

The sexy snapshot already has more than 7,300 fan comments and counting:

amy_ripplefitness: "Omfg - it's a fantasy come true for me! Agh!!"

thatonemakennagirl: "Wait is she lesbian? I wont judge i just want to know."

sumenties: "Please! Propose her <3. You both are made for each other <3."

rdenizfenty: "I kissed a girl [and] I liked it... YES :)."

evyatar126: "Love rihanna,love katy, love this pic."

The "Pour It Up" songstress just celebrated her 27th birthday on February 20 (2015). Perhaps the "Dark Horse" crooner couldn't make it to RiRi's official birthday bash. Rumors suggest that Drake's ex is currently "hooking-up" with hottie Leonardo DiCaprio. In fact, the 40-year-old award-winning actor allegedly hosted the wild surprise party for his kinky "friends with benefits!" Obviously, former flame Chris Brown was not invited (although Breezy does approve of Rihanna's new man... for now).

Knowing that things are working-out again betwen Chrianna, wonder if Karrueche Tran's worried at all?
