CELEBRITY Masterchef fans were livid after John Torode 'stole' Gregg Wallace's legendary catchphrase.
The second week of heats began with five new celebrities taking part.
They were former boxing champ Chris Eubank, musician Gareth Malone, Call the Midwife's Cliff Parisi, All Saints singer Melanie Blatt and reality star MoJo.
Judges Gregg and John asked the celebrities to prepare a dish, sweet or savoury, and Melanie decided to make a chocolate and peanut butter cheesecake.
As the cameras watched the 47-year-old mix her ingredients, John said: "That's inspired, as long as we've got a nice buttery biscuit base, as long as that cheesecake topping is firm, lots of peanut butter, lots and lots of chocolate....absolutely brilliant."
He added: "You know what, I think Mel's a bit of a cook."

However, fans immediately picked up on the fact John had uttered the immortal words usually reserved for Gregg.
The 57-year-old has said "buttery biscuit base" so much over the years it was turned into remixed tune in 2013.
Suffice to say, the track went viral and the catchphrase has belonged to Gregg ever since.
So the fact that John decided to steal it off him in the latest episode got Celebrity Masterchef fans talking.
