The quiz show host admitted it was a stand out moment having the Steps singer on set for the upcoming series of the BBC programme, and he couldn't resist getting him to perform a snippet from one of the pop group's beloved hits.

As reported by the Daily Star, he said: "My favourite moment was meeting H. What a total joy that man is.

"Obvously, I didn't make him do the rap from '5, 6, 7, 8', because that would have been a bit cheap... Hang on, no, I did make him do that. He nailed it."

Rick, 39, was also impressed by 'Silent Witness' actress Liz Carr - or at least her fashion sense.

He added: "She wore some sick boots and I really liked them."

Last month, it was revealed that 'Impossible' - which will replace hugely popular BBC quiz show 'Pointless' during its annual break - would be back with a host of famous faces taking part.

A spokeswoman said: "Following the popularity of the last three series of 'Impossible' in the early afternoons, we are looking forward to giving more viewers the chance to watch the hit quiz at 5.15pm on BBC One."

Also amongst the 18 stars lined up for the new series will be Vicky Pattison, Russell Kane, Debbie McGee and Anton Du Beke.

Each episode will see the famous contestants compete for £10,000 for their chosen charity over the course of six episodes.
