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.
