Rumor has it that R&B prince Chris Brown is kept on a pretty short leash by his own R&B princess, Rihanna. Rihanna allegedly exerts a whole lot of effort to make sure that her man doesn't stray in any way. Considering that both of these superstars live very hectic and public lifestyles, that definitely seems like a lot of hard work.

The "Distrubia" vixen reportedly handed the "Kiss Kiss" heartthrob a lengthy and detailed lists of things he can and can't do during his tour of Europe. The most prominent items on the list are the restrictions she gave him regarding when and where he can interact with other people of the opposite sex. Rihanna also refuses to allow any photographs of him dancing with a girl who is not her at any club. It seems that Rihanna knows full well how aggressive some female fans can get.

"Rihanna has banned female members of his entourage from being alone with him in his room and said no girls can be there past midnight," a source reveals.

If that wasn't clingy enough, Rihanna also made efforts to fly halfway around the world just to keep her man in line in person during the holiday break. She has also made sure that she would come back to the United Kingdom just in time for his performance at the O2 Arena.

A pal of the couple reveals to a London rag: ""The reason for her trip to the UK was to keep an eye on Chris... she changed her schedule to see him on the set of his new video. It's a track called 'Freeze' with rapper T-Pain, who likes the ladies."

"Rihanna knew there would be plenty of girls in the music video, so she asked a member of her entourage to keep an eye on the dancers."
There has been a lot of hearsay lately about the couple being engaged. Photographs in recent weeks have revealed Rihanna sporting a gigantic and dazzling rock on her ring finger. It's been said that Chris asked her to be his wife when they were together for a New Year's Eve performance.
