Anton Danyluk and Belle Hassan split last month, citing their hectic work schedules.
However, before the break up they made an appearance as a couple on newly rebooted TV show Supermarket Sweep.
While on the show’s Love Island special, the pair got into a blazing row after failing the challenge.
Belle was visibly annoyed at Anton on the show, as she blamed him for their poor performance in the task.
She said: “I’m actually embarrassed, you spent 40 seconds on beans, realised you couldn’t find them and had five seconds to get all the other stuff.”
“What was that about? You are meant to be the good one at this.”
“Couldn’t see the beans man,” Anton replied.
“You spent like four hours on beans,” Belle sniped back.
Supermarket Sweep host Rylan Clark-Neal then joked about the show”ruining relationships” following the row.
