hitmaker Rihanna's is driving away boyfriend R&B singer Chris Brown with her clingy behaviour, a report claims.
Rihanna has been reportedly dating 19-year-old Brown for almost a year, but both singers have continually denied they are a couple, despite being clicked together in public several times.
Reports about a split between the two have been circulating on the internet for some time, and now a source close to the couple has told
magazine that the Barbados-born beauty is a clingy girlfriend who can't bear to let Brown out of her sight.
"She has to have Chris around her 24/7. If Chris is with her on a photo shoot and steps away for a second, she starts saying, 'Where did he go?', " the source said.
For her part, the 20-year-old
singer admits that being away from loved ones is difficult for her.
"My biggest challenge is being away from my family and friends, and all the people I love and I'm used to being around," the Grammy winner had told the publication in an interview earlier.
The source agrees.
"If Chris isn't with her, she wants to call and check in every second. She's crazy about him. She constantly talks about Chris."
Neither Rihanna,nor Brown have confirmed reports about the split.
