The reality show returns in June, with a second celebrity series starting straight after in August.
The Sun reports Corrie star Julie has agreed to a £300,000 deal to take part.
"Julie may be getting on a bit but she’s certainly game for a laugh," a supposed source told the newspaper. “Denise proved that the Corrie stars bring in a decent audience and don’t mind poking fun at themselves and having a laugh.
“Julie is keen as mustard to get in the house and is already talking about winning.”
Meanwhile comedian Julian Clary is also set to enter, having been offered a £325,000 fee.
"He is not afraid to speak his mind and it’s usually in a comical way," the source added. “Big Brother is an adult show so he won’t get any flak for coming out with outrageous comments.
“That’s why he will be getting so much cash.”
Other names recently linked to the show include Nadine Coyle and Cheryl Ferigson.
