With eight chefs judging the Panna cottas, the decision was razor-thin as Denise edged Catherine’s by five votes to three.
After hearing she was staying in the competition, Denise was stunned, saying to the ITV hosts: “This is the biggest shock of my life.”
Catherine remained in good spirits, however, although she admitted: “I’m gutted, really gutted, I’ve loved it.
“But well done, babe. I’m so chuffed for you,” she added to Denise before saying her farewells.
