Things got very heated when IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua came face to face with undefeated challenger Jarrell Miller at a press conference on Tuesday in New York City.

Joshua will defend his belts against Miller on June 1 at Madison Square Garden in New York City.

The contest will mark Joshua's debut bout on United States soil.

The two boxers squared up at the presser, which led to Miller shoving the champion with force.

They had a similar confrontation back in July 2018, when Miller confronted Joshua at a DAZN press conference, also in New York City.

Joshua's bout with Miller came together after a planned April event fell part. Joshua had planned to fight on April 13 at Wembley Stadium in London, but he was unable to secure several possible opponents - like Dillian Whyte, Tyson Fury and Deontay Wilder.

Joshua has no fear of Miller's punching power and doubts that challenger, despite his size, is really a legit big hitter.

“I am going to knock him the f*** out. He is a drug abuser. He’s a kickboxer. I am going to knock him out. (Miller screams about Anthony’s mother.) Where’s your mother? I am paying her rent with this. She will come here and watch a real champion fight," Joshua said.

“Jarrell Miller is a little b*tch. I am going to throw this jab down his throat. For a guy that is 300 pounds, he punches like a fairy. June 1st - this is going to be a show. Come out and watch this one New York. I am not up here playing the gangster role.

"I really knock people out, look at his little hands. This is the first time he will sell out a show and it’s because of me. Of course he spends all day thinking about me and watching my fights, he has to – but it still won’t be good enough.”
