Possessive Kim bars RiRi from boyfriend Kanye West's dressing room

London, May 29 (ANI): Kim Kardashian is quite the possessive one as she has banned boyfriend Kanye West from letting Rihanna into his dressing room during his London gigs.

Rihanna had joined West and Jay-Z on stage at the O2 Arena. In February she was seen out with Kardashian's model brother Rob.

"Kim is incredibly protective of Kanye and doesn't want any women near him unless she is there - even his friends," the Sun quoted a source close to the rapper as saying.

"Rihanna wasn't even allowed to go into his dressing room without Kim being there. The fact she was linked to Kim's brother probably didn't help.

"It's crazy but Kim knows the attention Kanye gets when he's on tour - and she doesn't want any competition," the source added. (ANI)
