Antonio Brown finally got cut Wednesday night ... but it wasn't by the Pittsburgh Steelers.
The superstar WR was one of the celebrity performers on "The Masked Singer" -- and while the show was taped months ago, his song choice proved insanely relevant when it aired last night.
Disguised in a hippo mask, Brown performed Bobby Brown's "My Prerogative" -- which includes the famous lyrics. "Everybody's talkin' all this stuff about me. Why don't they just let me live?"
It's almost like he knew he was gonna be in the middle of a super nasty public feud with his team when he taped the show.
