Matt Preston is undoubtedly the kind but fair judge on Masterchef Australia.
Armed with his sophisticated tongue and charming cravat - the food critic's charisma has earned him a legion of fans.
So you can imagine our horror when the beloved TV star was recorded chucking his coffee.
WATCH IT BELOW.
Before you sling your cravats to the side, the shocking footage is a prank thanks to the cheeky team at KIIS FM.
With the classic hidden camera prank, the coffee guy from Kyle and Jackie O's HQ was left in tatters.
Barista John Nicholson gave Matt, 57, a cup of take-away coffee.
"Hi, how are you going? Welcome!" John said.
Responding the way anyone would in that situation, John told his colleague, "Matt Preston just threw the coffee in the bin!"
Don't freak out John, it was all part of a terrible rouse in the name of a good old fashioned prank.
