Rihanna turns 25 years old today (February 20th) and she may be celebrating by her lonesome. There is chatter that the sexy singer and her bad boy boyfriend, Chris Brown, have called it quits yet again.

"Chris and Rihanna had a big bust-up at the Grammys over Drake," SUN reports via an unnamed source.

"She was messaging him and Chris saw and it didn’t go down well,” the source adds. “Since that night they have barely spoken and have been doing their own things.”

Wasn't it text-messaging that led to that beat-down back in 2009? These two need to get it together.
