Former Loose Women star Denise is joining the soap for one episode as Kyle's mum Alison.
Denise told What's On TV: "It was a lovely reception at Elstree! It wasn't until I was there that I realised just how many people I knew in the cast. It was like a reunion of old friends. I saw Barbara and I saw Natalie, Bonnie and a few of my northern friends too like Poppy Rush. There was like a little northern corner going on.
"It was lovely to meet Riley, who plays Kyle. He said he'd watched me on screen since he was little so that was lovely. I felt like I'd been there for ages."
However, Denise, who won the ninth series of Celebrity Big Brother in 2012, said that she couldn't quite believe she was in Walford.
"No matter how long in the tooth you get it's always exciting to become part of something that you've watched for years," she continued. "As soon as I arrived I did a scene in the Square and I remember thinking 'Oh my god! I'm in Walford!'
"It was so bizarre. I felt very proud to be part of it. I couldn't quite believe I was there after having watched it for years."
Denise, who is also known for her role as Natalie Barnes in Coronation Street from 1997–2000, added: "Corrie was quite a while ago now, but I feel very proud to have been part of two British institutions."
Soap roles aside, Denise's other acting credits include Doctors, Boy Meets Girl, Waterloo Road, Down to Earth and Holby City.
