Fans have begun to claim that I'm A Celebrity... Get Me Out Of Here! favourite, Kiosk Keith, may not be all that he seems. 

The self-professed 'employee of the month' runs the Outback Shack, where the celebs spend their hard-earned Dingo Dollars on questions, in return for camp treats.

Keith gives the camp a call, and asks the question in a gruff, outback appropriate voice - which fans over the years have come to know and love.

However, fans are beginning to become suspicious about the legitimacy of Keith's voice on the other end of the phone.

These conspiracy theories have stemmed from the fact that viewers don't actually see Keith speak when the Dingo Dollar Challenge is asked - only hear him through the phone back at camp.

One fan said: "So I've never actually seen Kiosk Keith's mouth move… Please tell me it is his voice on the phone??? What if it's all a fabrication!" 

Another agreed: "You hear Kiosk Keith's voice in the Dingo Dollar Trial, but never see him talk. Is it really Keith's voice?" 

Other fans have begun wildly speculating online: "I feel like Kiosk Keith probably has a really high pitched voice in real life #ImACeleb."

One more claimed: "I'm convinced that Sean Dyche is the voice of Kiosk Keith #ImACelebrity2017."

These speculations follow the return of Kiosk Keith after a mysterious absence this week, where the fan favourite was replaced by Kiosk Kath - who viewers also did not see talking.

I'm A Celebrity… Get Me Out Of Here! continues tonight at 9pm on ITV.
