Floyd Mayweather -- Adrien Broner's Bunkin' With Me ... 'Til He Feels Better (VIDEO)

Floyd Mayweather is coming to the rescue of his ex-enemy Adrien Broner ... taking the boxing star into his home after Adrien's Internet suicide scare ... TMZ Sports has learned.

Floyd's reps tell us Mayweather saw the post, and reached out to Adrien, inviting him to crash in his Vegas mansion until AB is feeling better.

"Floyd is taking care of Adrien" ... says the rep.

Looks like the healing has already begun ... the two men hit up the Lakers game in Sin City Thursday night ... and were tooling all over the strip in Floyd's million dollar Bugatti.
