YouTube pranksters Kristen Hanby and Vitaly will finally step into the ring to settle their vicious rivalry tonight at the OVO Arena Wembley.
The social media influencers have a massive combined following well over 20million people, and they have shared numerous brutal words in the build-up to their grudge fight.
Russian Vitaly Zdorovetskiy has given up his life of drinking, drug abuse and steroids in an effort to live a cleaner lifestyle ahead of his boxing debut.
Meanwhile Hanby, a much naturally smaller man, says he's been eating chocolate and takeaways in an effort to get up to his rival's weight for the fight.
The pair have almost come to blows on a number of occasions during fight week, including a wild open workout, and tonight get the chance to throw hands in the ring.

Vitaly : "I feel bad, I really do - I've seen him sparring, he performed on stage, he looks like a joke; he's a street fighter and this is boxing!
"I'm a man of my word - absolutely I will knock him out, you will see.
"The relationship is done, he talked s*** about my mother, I did talk s*** about his grandmother, I take responsibility for that but mothers are different.
"He's going to get slapped around, it's a Rottweiler against a Chihuahua in the ring, I'm going to tear him apart.
"He's going to regret this - it's going to hurt.
"A bull couldn't knock me out, how is someone going to tell me Kristen Hanby can knock me out?"

Kristen Hanby : "He's a dozy idiot, I saw a clip of him sparring the other day and I couldn't stop laughing.
"I screen recorded it and I've watched it back 30 times, he's pathetic - he's talking all this stuff but he's getting slept!
"I don't know where he's getting this 60 seconds from, I don't know what he's been taking, he's not going to even land a clean punch on me.
"I'm going to stop him, I can see it now the referee is going to jump in and be saying 'he's had enough, he's had enough, he can't breathe!'
"He's going to need the referee to get me off him."
