Rihanna’s friends claim she is so obsessed with boyfriend Chris Brown she can’t let him out of her sight for more than a few moments.

“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?’” a source close to the Barbados-born pop star reveals in this week’s edition of OK!

“If Chris isn’t with her, she wants to call and check in every second. She’s crazy about him. Rihanna constantly talks about Chris.”

The 20-year-old singer has been dating Chris, 19, since 2007.
