Hosts Ant McPartlin and Declan Donnelly said: “There are going to be three little boys just jumping up and down for joy!” referring to the three young sons the 35-year-old author shares with her husband, McFly’s Tom Fletcher.
Asked how she felt Fletcher said: “I can’t believe it. People have literally picked up their phones and voted. I just can’t believe it - ask me in a week!”
The vlogger struggled at times during the three week reality show with being away from her children - Buzz, six, Buddy, four, and Max, two.
But she became a mother-figure in the castle with her fellow celebrities and earned the nickname “Mamma Gi”.
Her musician husband Tom Fletcher wrote on Instagram: “Me & the boys are SO PROUD of everything you’ve represented over the past few weeks. Strength. Happiness. Kindness. Compassion. Questionable choices of music.
“Jokes aside this has just confirmed what we knew all along… you are THE QUEEN! Thanks so much to everyone that voted for Gi and backed her, the support we’ve had has been truly amazing! She is a genuinely brilliant woman, wear that crown with pride Mumma Gi! Me and the boys can’t wait to see you soon.”
Reflecting on her time in the camp, Ant and Dec laughed at Fletcher for being so excited when the celebrities were given some garlic to season their cooking.
Fletcher, whose brother is The Only Way Is Essex star Mario Falcone, laughed; “Well, I’m Italian, of course I love garlic!”
Radio One presenter Jordan North, 30, came second in the show.
He said: “Absolutely fantastic, I couldn’t have lost to anyone better, been runner-up to anyone better. She’s the kindest person I ever met and she deserves this.”
The radio DJ North made a big impression on viewers from the very first episode when he vomited while abseiling down a cliff in the very first challenge. He was repeatedly voted to do trials involving snakes and creepy crawlies.
Looking back on facing his fears in the trials North said: “Stupidly I said I thought I could get away with avoiding doing any trials and maybe come out midway! And then I spewed on a cliff.”
During trials North would shout about going to his “happy place”.
North, who grew up in Burnley, had previously revealed his happy place was Turf Moor - the home stadium of his favourite football team Burnley FC.
He said: “That is my happiest place - when I’m on Turf Moor with my dad, my uncle’s, my cousins my brothers drinking and watching football.”
TV presenter Vernon Kay, 46, was placed second runner-up on the ITV reality show.
Asked by Ant and Dec how he felt about coming third he said: “Amazing. I’m over the moon to get third place because it’s been an awesome camp.”
The game show host admitted he had been surprised to have made the final, and was shocked when EastEnders star Shane Richie, 56, left the castle on Thursday.
He said: “I’m surprised because there were some really strong characters in there.
“Last night when Shane left it was a real surprise, he’s been the morale in camp. We’ve all had some big dips and we needed that to get through.”
Ant and Dec revealed Kay had phoned them up before he entered the castle to confess how nervous he was feeling.
Kay confessed: “I was nervous. It was everything and more, and I think if anyone in the future gets asked to do it, don’t even hesitate. There’s something about being in a confined space with 11 strangers - you have to be yourself.”
Kay had said he went on the sow because he wanted to make his wife, Strictly Come Dancing host Tess Daly, 51, and daughters Phoebe, 16, and Amber, 11 proud, and he felt he had achieved that.
He said: “Third place for me is more than my expectations.”
Due to the coronavirus pandemic, I’m A Celebrity was filmed at Gwrych Castle in north Wales this year, instead of the Australian jungle.
This year’s contestants included Olympic athlete Sir Mo Farah, 37, EastEnders actor Shane Richie, 56, and Corrie star Beverley Callard, 63.
