Rihanna spent her birthday in Hawaii with boyfriend Chris Brown. She posted a photo with her on-again beau, along with the caption “Pour it up pour it up! #birthdaybehavior.”

Just days ago, it was reported that Rihanna and Brown had allegedly broken up over text messages she sent to rapper Drake.

“Chris and Rihanna had a big bust-up at the Grammys over Drake," a source told the Sun. "She was messaging him, and Chris saw, and it didn’t go down well. Since that night, they have barely spoken and have been doing their own things. For now, they have split up, but they will probably make up at some point.”

Drake and Rihanna are rumored to have had a brief fling before going their separate ways last year.

But it seems Rihanna and Brown are still going strong.

The couple dated for two years before the relationship ended violently, when Brown attacked Rihanna while driving in 2009.

But back in February, Rihanna was featured on the cover of Rolling Stone magazine and admitted that she being with Brown fulfills her.

"I decided it was more important for me to be happy, and I wasn't going to let anybody's opinion get in the way of that,” she said. “Even if it's a mistake, it's my mistake. After being tormented for so many years, being angry and dark, I'd rather just live my truth and take the backlash. I can handle it."

Katy Perry, who is rumored to have distanced herself from the Barbadian stunner, even took the time to write her on Twitter. Just last week, Us Weekly reported that Perry did not want to rekindle her friendship with Rihanna, because she was upset the "Diamonds" singer reconciled with Brown.

“They aren't tight anymore, because Katy doesn't approve of Rihanna dating Chris Brown,” a source told the publication.

But Perry tweeted Rihanna on her 25th birthday, saying, "HAPPIEST 25TH BIRTHDAY to my baby girl ‪@rihanna‬! I wish I could b there drinking Mai-Tais & telling haters to eat a [expletive] w/u! [sic].”
