Rihanna is reportedly vexed over Natalie Nunn of Bad Girls Club making a move on her first cousin, Tee-Jay.

A source tells RadarOnline.com, "Natalie Nunn is crazy in love with Rihanna's cousin, and she's smokin' mad."  Apparently, Nunn and Rihanna’s relative “have been in Los Angeles for over a month together, and Tee-Jay hasn't gone home or visited Rihanna so she wrote a nasty tweet." The tweet in question: "@Natalie Nunn U made My cous go MIA on a Mohf**ka."

If the rumors are true, it wouldn’t be the first beef the Bad Girls Club star has had with a celebrity.  Over the weekend, Nunn and Amber Rose engaged in an online back and forth via Twitter over Rose’s relationship with Nunn’s ex, rapper Wiz Khalifa.
