An unlikely star has emerged from this year's I'm A Celebrity. Kiosk Keith, as he is known, makes but a fleeting appearance on each episode. But even in those few minutes he seems to have made his presence strongly felt, as every night viewers eagerly wait for the Dingo Dollar Man to show up on-screen with his now legendary blank face.

So who exactly is Kiosk Keith and why is he stealing the limelight from the host of celebs including British boxing champ Amir Khan? Here's everything we know about him so far:

Who is Kiosk Keith?

In the show, Kiosk Keith never speaks on camera and has become famous for his brooding demeanour. This mysterious personality has made him an enigma to a growing fan base.

Very little is known of Kiosk Keith's life apart from the fact that he is the quiet star of I'm A Celebrity.

His Twitter bio gives fans little insight into his life. It reads: "Aussie LAD born and bred.

Employee of the month at The Outback Shack. I'm the biggest Celebrity in I'm a Celebrity."

It's hard to comment on the "Employee of the month" claim since it's really a one man job but he just might be right about that last statement.

What is Kiosk Keith's job?

Kiosk Keith's job is to man the Outback Shack where winners of the day's Dingo Dollar challenge come in to collect treats.

But the stern moustached man isn't going to let the celebs have it easy. Before treats like marshmallows and chocolate dipped fruits are handed out contestants have to answer a question.

He calls up the camp's phone booth and if the celebs back in camp answer the question correctly, they are handsomely rewarded, if not, Kiosk Keith is more than happy to slam the Shack shutter on their faces.

This has become the classic Kiosk Keith move and while the celebs return without goodies, the viewers seem to love watching him shut them out.

Outside the I'm A Celeb world, however, it's anyone's guess what the Aussie's job is.

Ant continued: "He's assured us he'll be back very shortly as soon as he's dealt with some complicated personal issues."

After which Dec revealed: "He's got the thrupenny bits."

Whether Kiosk Kath is related to Kiosk Keith wasn't reported.

The viewers sorely missed the jungle legend but some also suspected that maybe he was just making an excuse to stay indoors on the rainiest day in camp so far.
