Floyd Mayweather Jr. retired last September with a flawless 49-0 record.

But since recently saying "All Lives Matter," the retired boxing champ is taking losses left and right out here.

A couple of hours after T.I. rocked Mayweather on Wednesday, calling his views "socially irresponsible" and undermining of Black Lives Matter, model Jessica White took to her Instagram account and landed knockout punches of her own.

White took it there, evoking Mayweather's domestic violence history with his ex in asking him how he believes "all lives matter."

Ouch.

Take a look at White's scathing post.

In case you missed it, here's Mayweather's recent "All Lives Matter" comments.

Welp. Sounds like a first-round KO to us.

Think he'll respond to Tip or Jessica?
