Kourtney and Khloe Kardashian are wanted for the next series of 'I'm A Celebrity... Get Me Out of Here!'.

The US reality TV stars could land the ITV jungle endurance show's highest-ever fees if they agree to take part in this year's contest - though programme chiefs are said to only want the sisters as they are a more realistic target than their more famous sibling Kim Kardashian.

A source told the Daily Star newspaper: "'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."

Though no names have yet been confirmed for the next series of the programme, a number of stars have expressed an interest in taking part.

JLS singer Marvin Humes admitted he is a fan of the show and would consider entering the camp when the group split later this year.

Asked his future plans, he said: "I might do 'I'm a Celebrity...'. I like the show."

Troubled former soccer star Paul Gascoigne has been approached for the show several times and is finally ready to say yes following another stint in rehab to treat his alcoholism.

He said recently: "They asked a while back, but I wasn't right and said no "When sober, I'm up for anything, but when drinking, I don't want to do anything. I won't say what they offered, as other celebrities would complain they weren't given as much. But it was a lot.

"I've no problem eating insects, and now I'd be there like a shot."
