The 'Keeping up with the Kardashians' stars will be dubbed as the international stars on the upcoming television series, reported Daily Star.

"'I'm A Celebrity' could be set to offer their biggest ever fee to secure the girls. In an ideal world they'd love to get Kim in the Aussie jungle but they know that would never happen. So they think her sisters are the next best thing and would bring lots of drama and publicity to the show," a source said.
