Anthony Joshua confirms he was due to fight Cassius Chaney in Saudi Arabia this weekend.
Jake Paul says Chaney has been in his camp and he's "already dealt" with him.
Anthony Joshua is having some back-and-forth with host and boxing journalist Ariel Helwani.
Helwani says Jake "deserves credit", but Joshua asks "do I not deserve credit?"

"I have the power and timing. I'm a tricky knockout artist and people don't give me credit. I have the timing and tricks up my sleeve to land a shot on this guy that he won't see coming."
Anthony Joshua on whether this fight is similar to when he fought Francis Ngannou:
"Francis Ngannou and Jake are different animals. Ngannou hadn't boxed before - he's bigger and powerful but Jake is quicker.
"Ngannou is upright but Jake doesn't do that. I'm not comparing. It's just about what happens at the end of the night. I want to hurt him."

"I'm going to break his face and break his body. I'm here to prove I'm the better fighter and will do that until I stop fighting.
"My focus is on Jake Paul."
Jake Paul on ruining Anthony Joshua's plans:
"It's a massive mistake to look past this fight. I'm knocking this guy out and becoming the CEO of Matchroom Boxing.
"It's going to be me v Tyson Fury next year.
"Look what happened when they last came to American. This is Andy Ruiz 2.0."
Anthony Joshua on who he's been training with:
"I won't be trained by Ben Davison. I've been training with team Usyk. He's one of the best in the world - no he's the best in the world."
Anthony Joshua confirms he can't weigh in more than 245lb but has no rehydration clause.
On how much he will weigh on fight night, Jake Paul said:
"I was cutting down for Gervonta but I expect 215lb or 225lb."
Anthony Joshua says he admires the chain Jake Paul is wearing around his neck and Paul offers to put it on the line if he loses.
This is all very cordial.
Jake Paul seems confident:
"I've already won at every single thing in life, I've accomplished all my dreams.
"I've become the biggest YouTuber in the world and had the most viewed fight in the history of boxing.
"I've never been knocked down or knocked out even in training.
"This is no different to a soccer player losing at the World Cup. If I take a punch like Francis Ngannou did then let's see if I get up.
"He has to deal with me too."
Jake Paul on whether he can win:
"He's one of the best heavyweights ever but I believe fighting a smaller man is difficult because of the speed. All his power is great but I just have to avoid that one shot for eight rounds and I believe I can do that.
"When I'm bouncing around the ring I know I can do that and score points.
"People say 'I respect Paul for getting in there', no I'm going to win."
Anthony Joshua is asked about the negativity surrounding this fight:
"I don't address people that are against me. Why would I be worried about negative comments. I focus on people who support me."
Anthony Joshua said:
"I don't think Jake is crazy, I think he's a logical person.
"All he needs is belief in himself and I need that in myself. If we listen everyone else maybe we wouldn't be here today.
"Good luck to him."
Anthony Joshua:
"You've got to credit to Jake and his team for reaching out.
"I wanted to take 12 months out of the game and get back to work. I was planning on fighting anyway and this opportunity presented itself.
"It's massive, colossal - Jake Paul v Anthony Joshua, we're bringing the whole world together to watch this."
Jake Paul continues:
"Joshua was always in the plans after Gervonta. Tommy Fury was scared, Ryan Garcia was scared and Terence Crawford wanted to do it later in the year."
Jake Paul is up first, he's asked why he is taking this fight:
"I like to challenge myself. I'm here to go out and shock the world.
"I see what he's capable of but I'm ready for a war.
"I've got to where I am today because of delusion. No one ever thought this would be possible when I started boxing."
The build-up to these news conferences can be over the top sometimes but no danger of that today.
Anthony Joshua has just been announced on to the stage.
We're diving right in and you can watch it all unfold at the top of this page.
Image source, Getty ImagesAs the British boxing media was preparing to head to Canary Wharf for a news conference to promote Chris Eubank Jr and Conor Benn eight days ago, rumours began circulating that Jake Paul and Anthony Joshua were set to fight in December.
Initial reports that a deal was close were wide of the mark but talks were under way.
It came after Paul's scheduled bout with Gervonta Davis was cancelled after the lightweight world champion was accused of battery, false imprisonment and kidnapping in a civil lawsuit by his ex-girlfriend.
On Monday, Paul v Joshua was officially confirmed.
Image source, Getty ImagesWe're back to bring you live text coverage of another news conference.
After hearing from five world champions yesterday in the build-up to Saturday's stacked card in Riyadh, Saudi Arabia, today is going to be a little different.
Two-time heavyweight champion Anthony Joshua and YouTuber-turned-boxer Jake Paul - yep, that's where we are with crossover boxing right now - will be speaking for the first time since their fight was announced.
Who knows how this next hour or so could play out.
