XXXTentacion says he got jumped by Migos in L.A. — and even posted video of what appears to be one of its members walking away from the fight … plus Cardi B’s photo.

X went on an Instagram rant Monday claiming he’d just been jumped by the rap trio, adding they allegedly pulled a gun on him during the scuffle.

He then deleted almost every post from his IG page and left only 2 — a video of what he claims is Takeoff walking away from the brawl … and a pic of Offset‘s fiance, Cardi. He later deleted both posts.

Unclear what set off the alleged jumping, but whatever the beef is … it’s probably only going to get worse now that X got Cardi involved.

XXXTentacion Apologizes to Migos After Blaming Them for Attack

XXXTentacion posted surveillance video of the alleged Migos jumping, and immediately had to apologize to them … ’cause it turns out it wasn’t them who attacked him.

X posted the security footage Tuesday, as well as a pic of the 2 guys who actually appeared to jump him. Neither of the guys are Migos members.

As we reported, X initially thought one of the attackers was Takeoff, and blasted him on social media. He also posted a pic of Offset’s fiancee, Cardi B.

For the record, the 2 alleged assailants were rockin’ “Migo Gang” pendants — but it’s unclear if they have any real connection with the rappers.

X said to Takeoff, in an IG comment, ”From the Bottom of my heart I apologize to you, you only caught in the cross fire of your blood line, blessings.”
