But the press conference soon turned heated as angry Mayweather sparked a homophobic storm by labelling McGregor a “f****t”.

The outburst was in response to his rival's alleged racist jibe, with the American accusing the UFC ace of insulting black people.

McGregor appeared to use the term “dancing monkeys” in relation to an all-black gym from a scene in 1982 movie Rocky III.

The Irishman denied making racial slurs but fight rival Mayweather insisted: “He totally disrespected black women. He called black people monkeys.

"He disrespected the mother of my daughter. I’m not gonna stoop that low.

“Some levels you just don’t cross.”

McGregor’s comments came on the New York leg of the worldwide tour to promote their £1BILLION Las Vegas super-fight on August 27.

He was asked on US talk show Jimmy Kimmel Live! who would win between him and Sylvester Stallone’s character in Rocky III.

McGregor replied: “Rocky III, that’s the one with the dancing monkeys in the gym.”

Mayweather's homophobic slur was made in front of 12,000 fight fans at Wembley Arena.

The American fighter called McGregor a “punk, f****t, h** and b***h” in a foul-mouthed blast.
