The actress revealed that she was just generally talking about "people as housemates", after those at home questioned whether she was still friends with the Loose Women panelist.
Speaking exclusively to Express.co.uk, the 58-year-old addressed her remarks while championing Mind and Moonpig’s #PlantASmile campaign.
When asked if she regretted what she said, Denise commented: "No… I’m not going to go down that road.
"What I said on Bit On The Side was talking about people as housemates… no I don’t regret it, I said what I meant."

What I said on Bit On The Side was talking about people as housemates!
During her appearance on the Channel 5 spin-off, she had stated: "I think that she has got a strategy. I think that Coleen’s very good at the passive aggressive thing."
Denise went on to reveal that she hadn't been asked to appear in the All-stars series, but wouldn't have done it "in a million years".
"No, I won it. There would be no point in going in it again and not winning. It was a hollow victory… I’m more than happy watching it at home," she said.
Meanwhile, Denise is the ambassador of the #PlantASmile campaign. In aid of mental health charity Mind, it busts the myth of Blue Monday and highlights the importance of staying connected with loved ones all year round.

Denise Welch blasted the idea of Blue Monday
She explained: "I’m always pleased when a company like Moonpig forms an association with Mind. I’m worried Blue Monday is going to become the Mother’s Day for depressives – and it is only a bit of fun really…
"People are going to get fed up in January and deflated after Christmas, but there is a big difference between that and depressed."
Denise added: "I for a long time have encouraged people to reach out to those living with a mental health condition, less than 20 per cent would think to send a card for someone who is mentally ill compared with over 50 per cent."
