They have two children together; Darcey, 14, and William, 10.
Ahead of her husband’s health battle, she revealed Derek had proposed to her again following her stint on I’m A Celebrity… Get Me Out Of Here!.
She told You Magazine in January: “When Derek came to meet me after I left the jungle, he was planning to propose to me again [in front of the TV cameras], but he got overwhelmed and burst into tears.
“The kids leapt out and surprised me and Darcey said, ‘Oh Dad – you didn’t do it!’
“So he got down on one knee and proposed… and I said yes, obviously.”
