Logan Paul has joked he is planning to fight Hasbulla after the TikTok sensation called him out last week.
Paul was pictured on a FaceTime call with Hasbulla and Solomon Engel, the man who helped orchestrate the American's fight with Floyd Mayweather last year.
Hasbulla went viral on social media last year for his videos with fellow TikTok star Abdu Rozik, with the pair often trying to fight each other in their videos.
The pair - who both have a rare type of dwarfism - attended UFC 267 in Abu Dhabi last October and also came to blows whilst cageside.
UFC president Dana White didn't rule out the possibility of hosting a fight between the two rivals, but said Hasbulla's father would likely stop that from happening.
"I don't know if he wants to get involved," White said during an appearance on Pardon My Take.
"From what I hear, his father is super protective of him. If that's the case, you don't want your kid fighting."
It's not the first time Paul has jokingly called out the Russian, writing on Twitter last year: "get me to hasbulla".
Paul announced his retirement from boxing this month after fighting once as a professional in 2019 against fellow YouTube star KSI.
The pair had met in a white-collar bout the year before, fighting to a majority draw which set up the rematch that KSI won by split decision.
Paul didn't fight again for two years, going the distance with ring legend Mayweather last June in a fight that sold over one million pay-per-view buys.
But Paul has now put his boxing career aside to focus on the launch of his new drink Prime Energy alongside old rival KSI.

Much like UFC supremo White, Matchroom Boxing boss Eddie Hearn said he wouldn't "rule out" promoting the fight between Hasbulla and his counterpart Rozik.
But the idea of a fight involving the pair came was labelled "a show to make people laugh" by the Russian Dwarf Athletic Association last year.
“It's not even like a show fight. They get paid a lot of money and it’s a show to make people laugh," Uliana Podpalnaya said to Gazeta.Ru.
"There’s nothing serious about this, this isn’t sport. This is unethical, wrong, from my point of view.
"It seems to me that only on the one hand it can be correct and beautiful, if martial arts among small people are made a Paralympic sport."
