Paige VanZant is a professional wrestler now -- the ex-UFC star just signed a contract with All Elite Wrestling ... and is set to begin her training ASAP!!
PVZ literally signed her contract in the ring during an appearance at "AEW Dynamite" on Wednesday ... after coming out of the crowd and attacking wrestler Tay Conti from behind.
The run-in caused Conti's boyfriend, "Spanish God" Sammy Guevara, to lose his TNT championship to The Men of the Year's Scorpio Sky.
