According to The Sun, the duo will enter the house "midway through the series".
Winstone-Peters, who has appeared in The Bill, Minder and Midsomer Murders, describes himself as "confident, multifaceted and very outgoing". He also claims to be friends with Russell Brand.
On his Starnow profile, he adds: "I also work with my bride to be Ivy Pink (We got engaged in 2008 on Celebrity Mr & Mrs), we are the perfect reality TV couple for 2009. As we are both entertaining extroverted characters."
Other contestants rumoured to be entering the house this year include beauty queens Stephanie Holland and Karly Ashworth, a "Brazilian lad", a "wannabe from Pakistan" and a "cheeky joker" from Ireland.
