The troubled ex-NFL receiver shared the image to his Snapchat on Monday ... showing Gisele's face edited on top of another woman's naked body.
A caption was not included, so there's no explanation behind the decision to take another shot at Brady's ex-wife. The slide was later deleted ... but screenshots of AB's post quickly made rounds on Twitter.
It's yet another example of AB burning his Brady bridge to a crisp -- he's completely turned his back on his former teammate in recent months, despite TB12's continuous support throughout his off-field troubles.
He also went the bad photoshop route another time ... by putting his face onto Brady's body as Gisele had her arms wrapped around him.
AB seemingly tried to expose Brady by sharing a text conversation from 2021 last week ... in which the 7-time champ called Brown out for acting like "a young immature man that is selfish, self serving, irrational and irresponsible."
Safe to say Brady's message didn't get through to AB.
