John Torode says he and Greg Wallace are "like a married couple" on "MasterChef".
The presenters of the popular BBC cooking show have opened up about the disagreements they have had over contestants over the years, and how they still don't see eye-to-eye over the winner (Matt Dawson) of the celebrity spin-off in 2006.
Greg admitted to the latest issue of RadioTimes magazine: "There's a disagreement that still rumbles on from "Celebrity MasterChef" in 2006.
"We were choosing between Hardeep Singh Kohli and Matt Dawson in the final, and we still disagree now.
"Every now and again I bring it up when I'm feeling irritable."
Both Greg, 54, and John, 53 - who have co-hosted and judged the competition since 2005 - have admitted that they "push" one another to the limit with their squabbles - but know when to call it a day.
Greg continued: "I know when I look into John's eyes whether he seriously wants that person, I can look in his eyes and know if there's wiggle room, a chance that I can change his mind.
"But when he slams down a spoon and looks at me and says, "I'm telling you, there's no way they're cooking for me again as long as I live", he means it. Then I won't even bother."
Greg also confessed that he can't believe the show is still going after 15 years.
He continued: "We feel passionately about contestants so we'll always disagree.
"I'm just amazed we've been going for 15 years."
Commenting on their relationship on the show, John added: "We're like a married couple. We both stand our ground and stick our heels in and then sometimes, when it feels worth it, we push the point.
"If Gregg's got a tear in his eye, I know he really cares, and I'll cave."
"MasterChef" returns for a new series on Monday (11.02.19) on BBC One.
