American actor Sylvester Stallone was reportedly on hand to break up a fight between boxer Tony Bellew and an actor while on the set of his new film Creed.
The alleged incident is not understood to have been part of the movie, which is a spin-off of Rocky.
According to TMZ, Stallone 'went ballistic' when the altercation occurred and was quick to pull the pair apart, with the help of some others on set.
A studio representative is believed to have claimed that the incident did not get physical, but the website states that witnesses told them otherwise.
