EXCLUSIVE: Kim Kardashian 'insecure' about Kanye West working with Rihanna

Someone fire the jealousy klaxon as Kim Kardashian has been gripped by a green-eyed monster when it comes to Rihanna.

TheFIX has learnt that 33-year-old Kim isn't happy after watching behind-the-scenes pictures of husband Kanye West and Rihanna's latest music video.

"Rihanna’s got a perfect body," says the family insider. "She is a guy’s girl, doesn’t get too emotional, and likes to have no-strings-attached fun.

"When Kim saw the behind-the-scenes photos of their video shoot, she got crazy jealous.

"She started to blow up Kanye’s phone and said she wanted to drop by and see him immediately. She pouted when he got home and started to argue with him about coming home too late."

Well, who can blame her? Would you want your husband working with that hottie on a day-to-day basis?

However, the reality TV queen soon realised she was in the wrong and came-up with some anti-jealousy rules.

"She has to have free reign to check his phone whenever she wants, and he gets to check hers. No notice needed.

"They have each other’s pass codes for voicemail. She can check his Snapchat and WhatsUp text messages, and he has to check in with her a few times a day."

So, how did she convince Kanye? "She told him it's to stop them having a blow-up again about something silly," says the insider.

Well, nothing says healthy relationship like checking each other's phones every day?
