*The British tabloids are reporting that Kim Kardashian banned Rihanna from Kanye West’s dressing room during his recent “Watch the Throne” tour concerts at London’s 02.

According to The Sun newspaper, the reality star doesn’t want her rapper boyfriend hanging out with other women on his own, and with Rihanna’s flirtatious reputation, she wasn’t taking any chances when she wasn’t at The O2 arena for his shows with Jay-Z.

The Sun claims Kim is not a fan of Rihanna ever since the young singer was romantically linked to her brother Rob Kardashian several months ago.

A source told The Sun: ”Kim doesn’t want women near [Kanye] unless she is there – even friends. The fact Rihanna was linked to Rob probably didn’t help.”

Kim is also said to have ordered Kanye to leave a party in London last week after he spent too much time with other female partygoers instead of her.

A source said: ”Kim was all over Kanye at the start, but when he started to mix with other people she had a stern word and took him away from the party. He followed her orders with minimum fuss. He knows the deal.”
