Celebrity best friends Katy Perry and Rihanna have allegedly fallen out over Rihanna’s reconciliation with R’n’B singer Chris Brown. Although normally spotted on wild nights out together, giggling together at events or professing their love for each other over Twitter, the pair of feisty singers are now barely speaking.

The last time that they were seen together was at the MTV awards, where Rihanna was spotted kissing and hugging Chris Brown. Even though it was just a quick peck and a hug, it seemed a bit too friendly considering what Brown did to her.

Rhi-Rhi and Brown split in 2009 due to Brown’s assault on her after a pre-Grammy’s party. The “Rude Boy” singer was left battered and bruised and Brown allegedly threatened to kill her. A couple of months after the attack, she said in an interview on GMA with Diane Sawyer, “The thing that men don’t realize, when they hit a woman … the face, the broken arm, the black eye, it’s going to heal. That’s not …. the problem. It’s the scar inside. You flash back. You … remember it all the time.”

In the latter part of this year there have been several rumours of the couple reuniting and they have confirmed that they will are collaborating on Rhi-Rhi’s new album “Unapologetic” and Brown reportedly breaking up with his girlfriend Karrueche Tran. In August of this year, Rhianna broke down in an interview with Oprah Winfrey, explaining why she forgave both Brown and her abusive father, saying about Brown, “I just felt like he made that mistake because he needed help.”

Like a lot of women around the globe, Katy Perry thinks that her friend is making a BIG mistake letting Brown back into her life. The “Part of Me” singer said in an MTV interview, “We’ve had dinner, and that’s about it, I didn’t reach out to her after the incident. I think she is doing fine. I don’t know. Her personal life has probably already been blown out of proportion. I don’t really have to go into that. I’m sure she probably want’s a break.”

What is confusing everybody is this “incident” that she is referring to. Some think she may be referring to the kiss at the MTV awards, which is the first time that the supposedly-former couple have been spotted in public together since the split. Since the awards show, Rhi-Rhi has tweeted “@katyperry happy birthday lover!!!! #iwantsomeskittles” to her friend.

It isn’t the first time that their friendship has been strained.The Bajan beauty didn’t attend Perry’s wedding to English comedian Russell Brand due to last-minute schedule changes. She did however throw a legendary bachelorette party in Vegas, complete with a Cirque du Soleil performance.

Hopefully the two gorgeous singers will rekindle their friendship soon. As far as Chris Brown is concerned, Rhi-Rhi shouldn’t go near the woman-beating douchebag ever again!
