The TV host, 38, had the audience in stitches as she entered the ‘House of Jeff Brazier’ and began rolling her tongue while shimming up and down.

Holding either side of her chest, Holly continued to make the noise as she winked towards the boys and tried to act out the action of being flirty.

While all of this was taking place, show host Keith and guest Mark, 32, were pretending to hide behind a shelf.

The pair couldn’t help but poke fun at the This Morning presenter during the game and made a few rude remarks before successfully guessing the behaviour she was acting out.

Former Towie star Mark said: “Don’t answer keep her doing that. I like this next bit coming up.”

While Keith weighed in: “If you’re a teenage boy at home and your parents have gone out, get your tissues. This is my gift to you.”

Last week, Keith claimed that Holly could “win any drinking competition” after revealing that Celebrity Juice’s filming sessions are “fuelled by booze.”

The comedian, 45, and Holly will be joined by Paddy McGuinness when the show returns later this week.

Keith told New! Magazine: “She’s Holly Willough-boozy. She’ll always win a drinking competition. I don’t know how she does it!”

The Celebrity Juice host went on to explain how he wished he had Holly’s stamina when it comes to knocking back the booze and still making it to work the next day.

He told the publication: “Like at the National Television Awards, she gets boozed up and then goes to work the next day. I can’t do that. My next day is a write off!”

When asked how the Celebrity Juice panel manage to get away with so much on-air mischief, the host teased: “It is really naughty, but on the night it’s quite booze-fuelled naughtiness.

“Everyone has their inhibitions pushed to the kerb.”

Keith is currently filming the next series of Celebrity Juice, where Paddy McGuinness will replace Fearne Cotton.

Fearne Cotton quit the ITV2 show after 10 years of being a regular panellist on Celebrity Juice.

When news broke, the mum-of-two said: “After ten years of complete fun, I have decided to leave Celebrity Juice.

“It has been a joy to be part of this magnificent show and I wish the team the very best in future series.”

Celebrity Juice airs on Thursday March 21 at 10pm on ITV2.
