Phillip Schofield and Sarah Greene have reunited for the first time in 24 years to present 'This Morning' on Tuesday (04.04.17) after Holly Willoughby called in sick.

The pair previously hosted 'Going Live!' - a children's weekend show - together for six years almost two-and-a-half decades ago but proved they still very much have their on-screen chemistry, despite the time that has passed, when the blonde beauty stepped in to replace Phillip's regular co-host after she was struck down with a sickness bug.

Introducing the show this morning, Sarah said as she took prime position next to the silver fox: "I'm in a time warp. What's weird is it doesn't feel weird!"

Phillip added: "You look exactly the same!"

He then explained where his regular co-host is: "Holly is not well.

"There is a bug in the Willoughby-Baldwin household, and Belle [her daughter] is ill again. So she's not well and also having to cope with poorly children as well."

Prior to the show, Phillip teased that Sarah would be joining him on the programme.

He tweeted: "Well nostalgia fans, as poor @hollywills is still not well ... we're 'Going Live' on @thismorning with my co-host for the day. (sic)"

Holly's unexpected illness threw the show into chaos yesterday (03.04.17) when Rylan Clark-Neal - who presents the showbiz segment on the brunchtime series - stepped in for her at the last minute so that Phillip wasn't hosting the entire programme alone.

Phillip said at the time: "Holly's not well today so I've be given the most unlikely partner. I can't wait for this. They said Rylan was coming in and I said I'd do it on my own."
