Here's what McGregor, Mayweather said to each other at LA press event

Both American boxing star Floyd Mayweather and UFC star Conor McGregor have revealed what they said to each other during their press conference on Wednesday.

The much awaited battle between McGregor and Mayweather is all set to take place on August 26.

Both fighters in June took to social media to confirm the development, as Mayweather posted to Instagram saying "It's official!" while McGregor said "THE FIGHT IS ON," on Twitter.

Both McGregor and Mayweather kicked off a four-city, three-country international press tour, the first of which of which took place at the Staples Center in Los Angeles on Wednesday.

Mayweather, who is coming out of retirement to fight McGregor, had earlier said that he cannot pay off his tax liability from 2015 until he fights the MMA star.

As per the Guardian, during the press conference, McGregor made fun of Mayweather's clothes, mocked his unpaid tax bill and promised to knock the boxing great out in less than four rounds.

However, the American then got to shadowboxing, which amused McGregor.

Seeing this, McGregor laughed so much, brought the microphone to his lips and said, "Dance for me, boy!"

Meaweather, who was clearly pissed by McGregor's comment, stopped shadowboxing and started to stalk towards the latter, who quickly changed his tune.

"Dance for me, son! Dance for me!" McGregor called out as Mayweather returned to the podium.

Speaking to reporters after the face-off, McGregor told reporters, "He was trying to say something about the gloves and I was like 'you cried about the gloves'."

"He cried about the ounces of the gloves. Then he tried to say 'MMA next, we'll do'," mirror.co.uk quoted the two-division UFC champion as saying. I was like [wags his finger] 'you're talking s*** about stuff that you won't do'. Other than that it was just back-and-forth. The usual s****."

Meanwhile, Mayweather also revealed to the reporters what verbal exchanges were made between the two and said, "It was just trash-talking that fighters say to one another. Of course, he was saying how good he was. I was like, 'I don't have to tell you how good I am, you already know'."

"He was talking about gloves and saying he was going to knock me out. Yeah, that's what they all say," the American added.

The fight against McGregor, which will take place in Las Vegas, is expected to challenge financial and PPV records, despite the one-sided expectations.

Mayweather will seek his 50th career win against a two-division MMA champion who has never boxed a professional round.
