The format will see six celebrities attempting to "complete a variety of hilarious challenges".
The producers say: "With comedy rounds, great guests, and Rob at the helm, we're all set to be thoroughly entertained!"
The Sun reports a source as saying: "Rob is one of those figures who is as well liked by television executives as the viewers at home, so it was really only a matter of time before he got a vehicle that showcased him.
"It's fair to say he hasn't really had the big break he deserves since he started to gain a profile ten years ago - and this could be just what he needs.
"This is only a pilot but there are high hopes it will lead to a full series."
