Dom Joly played a trick on Gillian McKeith by sporting fun fancy dress for a practical joke.

The former Trigger Happy TV star crept up on his fellow I'm a Celebrity … Get Me Out of Here contestant, who did little but moan and scream since she got to the jungle.

However, the prank was made even better by the fact that he was wearing cockroach fancy dress, Unreality TV reports.

As expected, Gillian squealed before bursting into slightly hysterical laughter. Dom said he thought she'd had it a bit easily lately, so was in need of a scare.

Despite her protests that she is terrified of insects and hates everything in the jungle, the public voted Sheryl Gascoigne out at the weekend, leaving Gillian frightened of doing more of the dreaded Bushtucker Trials.

However, she was finally ousted last night (November 29th 2010), probably leaving producers fed up that there'll be no more on-screen fainting to boost ratings.
