West, 34, and fellow rapper Jay-Z are set to take their Watch The Throne tour to Europe and Kardashian is reportedly determined to get rid of any threat at the tour, reported Sun online.
"Kanye has a load of girls he's friends with. Most are stylists or from the fashion set but Kim's not happy about them being alone with him backstage.
"She sees how well he gets on with girls because of his sensitive side and has decided to rein in the entourage a bit. Kim is trying to put a stop to this as she doesn't want to look or feel awkward at any point," a source said.
The 31-year-old brunette beauty will be with him for the whole of the Watch The Throne ten-date UK tour, which kicked off at London's O2 Arena last night.
"She has her own area at the O2 so she can spend more time with Kanye. She realises he will need to do his thing with Jay-Z and the rest of the crew but she'll have somewhere for her and her pals to hang out," it added.
