Tommy Fury has been filmed involved in a fist fight with his brother in the street at 4am earlier this month.
Love Island star Tommy, 23, is seen topless and throwing punches in the footage.
The video, shared by The Sun, shows a topless Tommy stood at a bus stop in Altrincham, Greater Manchester as he spars with his brother Roman in the early hours of August 17.
He is wearing a pair of black shorts while a pal stands between himself and his sibling.
Molly-Mae Hague's boyfriend Tommy is then seen pushing the pal stood between the pair and throwing a punch while holding his other fist up towards his face.
He then pauses and holds his hands out in a gesture to suggest he is stopping.
But, then Tommy is later seen appearing to usher his brother over.
In a later clip, Tommy is seen throwing several punches at his brother again, also striking the pal stood between the two in the meantime.
The man in the middle then steps away as the professional boxer continues to throw jabs before the friend gets involved again.
Tommy's brother then walks towards him as the former Love Island star throws more punches and the pal then comes between the pair to break things up again before the clip cuts out.
Meanwhile, an onlooker told the publication how they witnessed the 4am sparring session as they were being picked up by a friend.
They explained: "After we put our bags in the boot we were about to drive off and then we saw Tommy topless.
"He was shouting at his brother and that’s what made us notice him."
The Mirror has contacted Tommy's representatives for comment.
Meanwhile, a source has told the publication the incident was nothing more than a play fight.
They said: "They weren’t in a row and were just messing around – he’s close to his brother and Tommy can fight – if he meant it, you’d see it in the video."
It is not known where Tommy's girlfriend Molly-Mae, 23, was at the time of the incident.
Molly-Mae has recently been away on a photoshoot for her new collection with Pretty Little Thing and later joined pal Maura Higgins in Paris to celebrate her new collection.
Speaking about the range, Molly-Mae filmed a vlog for the fashion brand during the shoot and said: "I think I'm shooting what could be my favourite collection yet.
"I know I say that every time but this one is so special."
Tommy and Molly have been dating since they met in the Love Island villa in 2019.
The pair coupled up in the villa and finished in second place during the finale. But, have gone from strength the strength since as the pair now own a lavish mansion in Manchester, which they car currently renovating.
