Tufnell will contest the Grand Final with ex-footballer John Fashanu and TV interior designer Linda Barker.
All three remaining contestants then had to complete a Bushtucker Trial to win food and Phil, who is tipped to win the ITV show, seemed to have the worst of them.
Beetles, ants and worms for tea!
He had to tuck into a not-so-tasty meal of live bugs including a live beetle, a handful of red ants, meal worms and a moth pupa.
Tufnell told Fash after the Trial: "that was probably the most disgusting thing I've ever had to do in my life."
Linda had to transfer a number of eels from one tank to another, while Fash had to wear a special hat with eels and goldfish in it.
