Former Geordie Shore star Vicky, 28, was crowned Queen of the Jungle on Sunday night's finale, beating competition from Union J singer George Shelley and TOWIEstar Ferne McCann.
Speaking on today's Loose Women, former I'm A Celebrity contestant Katie had nothing but praise for Vicky.
Katie said: "I think she deserved to win this show because she was ballsy and said what she thought. But she was a completely different person in Geordie Shore, more partying, sleeping with guys, I don't think she should regret it as if she hadn't done that show she wouldn't have had the chance to be on I'm A Celeb.
"She's really turned it around for herself. She has her clothing range out and said that she said she would like to be like me, which is flattering. But she's definitely turned it around and I'm sure we will see lots more of her."
Vicky has admitted she's overwhelmed to have won the show, saying after the result was announced. "I feel f**king amazing. This is the best feeling ever! It is completely surreal. I thought I would be one of the first people voted out, that he would get on with no one, nobody would know who I was and when they did, they would think I was a knob."
