It's been nearly three years since Floyd Mayweather threatened to "kill" Jake Paul ... but Logan Paul says his little brother is still taking the remark seriously, employing 24-hour security to this day.
Logan first explained to TMZ Sports back in 2021 that he and Jake were afraid Mayweather was being for real when he exclaimed "I'll kill you motherf***er" to the younger Paul following their now-famous "gotcha hat" encounter in Miami.
In a recent interview with Graham Bensinger, Logan said his brother is still so concerned over the words ... he's making sure a guard watches his back at all times.
"Jake has not been without a security guard since that moment," Logan said in a sitdown chat with Bensinger.
Logan said his brother's main worry was all the connections Floyd has in Miami ... alleging, "He's got goons who kill a man for $200."
The two didn't have any real issues, however, in the wake of the '21 incident -- at least, that was the case until 2023 ... when they both attended a Heat game in Miami.
You'll recall, Mayweather confronted Jake outside the arena following the tilt ... forcing the social media star to seek protection from cops.
Since then, it's been quiet ... although according to Logan, Jake's not taking any chances.
Logan also talked to Bensinger about potentially fighting Floyd again -- saying TBE actually offered him a rematch of their '21 bout in 2022 on short notice. But Logan said he didn't take it, knowing he'd need more time to prep.
As for if the guys ever got in the ring again, Logan was confident he'd come out with a win -- saying straight up, "I think I'd beat him."
