JAKE PAUL & KSI engaged in a heated Twitter brawl over the cost of Problem Child's upcoming pay per view.
Former Disney star Will face off with Hasim Rahman Jr, the son of former heavyweight champion Hasim Sr at Madison Square Garden on Aug 6.
Jake Paul was embroiled in a tense Twitter feud with KSI last night
The British YouTuber shot the first shot at his American counterpart
Paul will then be facing KSI at London’s O2 Arena - only three weeks after his fight with New York City.
YouTube star KSI will be battling Alex Wassabi, a fellow social media star, at the O2 in London on August 27.
Since his controversial split decision win over Paul's brother Logan, KSI (real name Olajide Olatunji) has not been in the ring.
Paul, who he has been aching to fight for the past two years, will face the Brit. The problem child will be at the corner of Wassabi in capital.
Things have heated up on social media between the pair after KSI took to Twitter and criticized the $60 PPV price to buy Paul's clash against Rahman Jr.
KSI began the row by sharing a fight poster with Paul and Rahman, and writing: "$60 PPV. I promise you that my PPV on August 27th will not exceed that amount.
The Problem Child responded, "No s*** dummy. I have one 'win. I have five. This is the KO of this year.
"You are fighting an influencer. I am fighting a legit 12-1 boxer. They are different. It is not fair to charge more than $10.

He stated, "Don't believe we don't understand how desperate it looks.
"No one cares so you have to pay to create hype lmao."
Paul joked and replied, "Thx for the retweet KSI' you have won the $1000 contest!"
This led to the following response: "Think about how much you need it." You have to pay people to go to your fight buddy's place, because that isn't selling.
The American seemed annoyed by the comment and stated that he made $45million last year, while he made weekly YouTube videos.
Paul took a screenshot from a text message he allegedly wrote to Logan, asking him to send a Grand over to KSI. He also mocked Logan's "plummeting Spotify streams", but it was the message above which drew a response from KSI.
He tweeted: "Na you still don't get it. You didn't care what platform made you who you were. It was constantly decried.
"I never did. Because I can now do/be anything I want, I'm glad to be a YouTuber. My guy, I think long-term. This is what you failed at."
Paul continued the argument, saying: "Imagine saying, "Yes, u made $45m, but i am a YouTuber and i'm proud!"
Undeterred, KSI replied: "My YouTube channels. Sidemen YouTube channels. Sides. XIX Vodka. Music/Tours. Hydration at its best Adidas. Misfits Boxing... Jake, think about it!
Paul, however, was not having it. He replied: "This dude's pushing 30 years old and flexing his collection YouTube channels."
