Source: Chris Brown Whipped By Rihanna

Not that you can really blame the man if he gets to date her, but rumors are surfacing that Rihanna goes to considerable lengths to keep Chris Brown in line.

The "Disturbia" singer gave CB, who she may or may not have gotten engaged to recently, a checklist of what he can and can’t do while on tour in Europe.

Atop of the list are tight restrictions on when and where he can hang out with other girls. She also doesn’t want to see pics of him dancing with girls in a club.

She knows how far fans go to get his attention.

“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,” says a source.

To top it all off, Rihanna flew half way around the world to check on Chris Brown over the holiday season. Moreover, has decided to come back to the UK again in time for his gig at The O2 on Sunday. Hey, better safe than sorry.

A friend told a London paper: “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 asked a member of her entourage to keep an eye on the dancers.”
