I'm A Celebrity... Get Me Out Of Here! contestant Arlene Phillips has admitted it was "very strange" when the group were evacuated from the castle last week.
Arlene and the other celebrities were forced to leave Gwrych Castle due to bad weather after Storm Arwen hit Wales.
After becoming the first camp mate to be voted off the show on Sunday evening, Arlene made an appearance on Monday's Good Morning Britain via video link.
Speaking to hosts Susanna Reid and Martin Lewis, Arlene explained: "We spent a day in the castle, we didn't know where we were going to go or what was going to happen.
"And then we were taken into isolation, we all had separate houses and there was some food waiting for us - we were totally isolated you know."
"It was very strange because you're out the castle but you're still in isolation," Arlene continued.
"For me it was great because I managed to get delivered my Josh Wood and I could do my roots and that was like the biggest thrill of a lifetime to go back without my roots showing, so it was a good thing for me!"
When Susanna asked: "What was it like in there?" referring to the castle, Arlene replied: "It's really tough in there, I had prepared myself for it but it's actually tougher than you think.
"But it's an adventure of a lifetime!" the former Strictly Come Dancing judge added.
During her exit chat with hosts Ant McPartlin and Declan Donnelly on Sunday evening, Arlene was asked whether she found it more difficult than she expected.
"Much harder. I psyched myself up, I was so prepared for it," she replied.
"I'd focused on why I was doing it and what I wanted to achieve... but it is hard.
"I'd watched it for so long and it's about overcoming fear," Arlene continued.
"It brings out something in you and it brings out a lot of emotions and thinking about your life."
Good Morning Britain airs weekdays at 6am on ITV and ITV Hub.
