The former Health Secretary is entering the camp late as a 'surprise' celebrity guest, but has already given an interview to The Sun newspaper about his decision to sign up to the ITV show while still a serving MP.
As hosts Ant and Dec launched the new series of the jungle reality show in Australia on Sunday night, viewers were introduced to the first 10 celebrity contestants.
Opening the show Donnelly said: "We'll be rolling out the welcome Matt for them very soon," and gave an exaggerated wink to camera.
While the show introduced former Radio 1 DJ Chris Moyles, Loose Women’s Charlene White, Love Island's Olivia Attwood, comedian Babatunde Aleshe, and Lioness footballer Jill Scott, viewers were all talking about the absent MP for West Suffolk.
Mike tweeted: "Any one else thinking ... "Where's #MattHancock when you need him?" #ImACeleb"
Lucy shared the opinion of many when she said: "Thinking about all the trials we can all vote Matt Hancock in for #ImACeleb"
Tony commented: "Just downloaded the im a celeb app time to vote for matt hancock to do every task. [sic]"
And like many other viewers anticipating the other contestants' reaction to the former Cabinet Minister's arrival Rosie tweeted: "Waiting for Matt Hancock to come in the jungle just to see everyone’s reactions #ImACeleb."
Kate posted: "I mean, it's going to be weeks of ritual humiliation for Matt Hancock, so what's not to like?"
Hancock will join the camp later in the week, along with comedian Seann Walsh, best known for being pictured kissing his married professional dance partner Katya Jones while he was competing in Strictly Come Dancing in 2018.
The former Health Secretary - who was forced to resign from government after his affair with advisor Gina Colangelo was exposed - revealed he turned down an offer from ITV to take part in the reality show twice, before making a last minute U-turn last week.
The 44-year-old father-of-three is still an elected MP for West Suffolk, meaning he is being paid an annual salary to serve his constituents.
He said his constituents are "still my first priority" and revealed he has agreed with producers that he can be reached at any point during filming if any "urgent constituency matter" arises.
I'm A Celebrity returned to the Australia, after two series filming at Gwrych Castle in north Wales due to restrictions around travel caused by the pandemic.
Among the other stars taking part this year are singer Boy George, former England rugby player and minor Royal Mike Tindall, who is married to the late Queen's granddaughter Zara Phillips.
