Rihanna has been spotted on numerous occasions of late clutching a bottle of beer as if her life depended on it, leading to speculation that she may have a drinking problem.

A source close to Chris Brown says the star has reached out to his former girlfriend with the hopes that she'll rein in her hard partying ways.

“Chris was really, really worried about her when he [heard] she was up drinking and partying… by herself," the source told Hollywood Life. "So he just wanted to reach out to her and show and little support, you know?”

He's said to have texted her: “Cut out all [that] drinking.”

She hasn't replied to him, though.
