Holly Willoughby goes wild as she pins Chris Ramsey and grabs his pants on air

THIS Morning’s Holly Willoughby is usually as calm and collected as it gets – but she was very different on TV last night.

The 41-year-old star went wild during the final ever episode of ITV’s Celebrity Juice.

The last game on the show saw whichever team could grab a piece of cardboard from the audience being crowned the ultimate champion.

Holly, 41 – who returned to the show as part of Emily Atack’s side – seemed determined to get her hands on it.

First she fell backwards down the stairs in a painful-looking tumble that saw her sprawled out on the studio steps while trying to tackle Fearne Cotton.

Then she leapt on top of Chris Ramsey, a member of the opposing Laura Whitmore team and straddled him while he was face down.

Cameras showed her grabbing the back of his underpants leaving the comedian’s screaming on the studio floor.

Chris, 36, later gasped: “I swear to God, that wedgie changed my religion.”

Even host Keith Lemon seemed shocked by Holly’s determination, saying: “She so wants to win.” The star replied: “Desperate.”

The mayhem unfolded when the teams were drawn at the end of the last Celebrity Juice on Thursday night.

Keith said: “How do we settle a draw? The only way I know to settle a draw is for the first person to come back here with a piece of cardboard which is being held by Johnny Vegas in the audience.”

In the end, Laura was the first to return the scrap of card, meaning her team was victorious.

Keith ended the last ever show saying: “Thanks for 14 years of fun and laughter. What an amazing time. I just want to say, for the final time ever, if I don’t see you through the week I’ll see you through the window.”
