CHRIS EUBANK JR trolled Conor Benn after his father asked him to pull out of the fight due to safety concerns.
The Brits are set to lock horns on October 8 at the O2 Arena.
To make it an equal fight the pair have agreed to weigh in at 157lbs, meaning Benn, 25, has to gain an extra 10lbs.
But Eubank, 33, usually fights at 160lbs and has fought at 168lbs in the past, and cutting weight could present a danger for the boxer.
Eubank previously stated he will only be able to fight at 60 per cent due to the cut and rehydration clause which limits Eubank’s weight the day after his weigh-in.
But he showed little care for his dieting as he enjoyed his birthday meal on Sunday however, and instead took time to troll his opponent on Instagram.

The boxer was filmed tucked into his birthday cake on a plate that was decorated with ‘60%’.
Eubank then filmed himself taking a huge bite of his sticky toffee pudding and ice cream dessert, with a caption that read: “Just can’t help myself.”
The fighter’s carefree antics come just a week after his father urged him not to fight Benn.
Eubank Sr is concerned by his son having to boil down and dehydrate for the fight and is fearful of losing another child following the suddean death of Sebastian from a heart attack aged 29.
Eubank Sr said: “This fight should not be allowed to happen, it is dangerous.
“I have given my advice and I will continue giving it because I know how dangerous weight cutting is.

“I have already lost one son, there is no way I am going to risk losing another.
“I have spoken to Conor Benn — who I regard as a brilliant fighter and a king — and he told me he was willing to fight at 160lb.
“So who has engineered this dangerous decision to limit my son?”
But Eubank Jr confirmed the fight will go ahead despite having a cheat day from his diet.
