'Is it it?' - Logan Paul and KSI fans are angry that Logan Paul announced they will not fight in the third fight following a social media tease.

After a cheeky social media stunt, Logan Paul and KSI had their fans fuming.

The YouTubers created a stir among their fans when they announced the 'Final Chapter', with many assuming it was a reference to their boxing rivalry.

Fans were furious when it was revealed that the pair were actually launching an Energy Drink together, and not announcing a trio of bouts.

The Instagram live stream revealed everything, which led to backlash online.

One user posted a comment on Instagram: "Not happy at all."

Parkerfeys wrote "Bro did us wrong."

Another said: "Who knew they'd announce a third fight?"

Caleb_cromwell agreed, saying: "This is not what I wanted."

Michael Goldstein also wrote: "You could have at least punched one another in the face for old time sake."

Yesterday it was announced that the two had become business partners. Prime Hydration is a new sports beverage.

During a livestream, Paul (26) and KSI (28), revealed that their new beverage is aiming to "rival many of the largest companies on Earth with their beverage," including Pepsi, Coke and Gatorade.

They were bitter rivals before they teamed up.

Paul and KSI met twice in the ring when they crossed over from social media to fight games.

Their fight at the Manchester Arena in 2018 ended in a draw. This was an impressive pay-per view success for an amateur event.

After a fight, they turned professional and Britain's KSI won the next meeting. His American opponent was given two points for punching him.
