The 'star' of Channel 4's Benefits Street was linked to the upcoming series last week.
“Dee will be brilliant on Celebrity Big Brother. She’ll play to win,” a pal of her’s teased to The Sun newspaper.
But now her agent Barry Tomes has insisted that she's too busy to take part.
He told the Daily Star newspaper today: “We couldn’t do it even if they made us that generous offer.
“I don’t know the dates, but I think it’s September and we’re shooting a cooking show through August and September.”
Rather than a stint on CBB, Dee – real name Deirdre Kelly – is now aiming to make herself into a celebrity chef.
After losing five stone, she now plans a TV series on cooking on a budget.
Her agent said: “I took her to France to train with a chef.
“She is a mum so she looks after her kids. She’s very much into fruit and fish and healthy eating. I’m very excited for her.”
Channel 5 did not comment on the CBB rumours.
