Ronda Rousey ain't the only UFC star gunnin' for the WWE ... Paige VanZant says she LOVES the pro wrestling biz, and is "definitely interested" in making the jump.
"If the knock comes onto my door, I'm taking it," Paige told TMZ Sports before adding ... "when the time is right."
PVZ also seemed pretty down to face Rousey in the ring ... especially if WWE lets 'em throw hands for real!
For now, VanZant's gonna stick with kickin' ass inside the Octagon. She's making her debut at 125 pounds this Sunday at UFC Fight Night 124 ... and says she's got BIG plans for 2018.
One of those plans involves the UFC ... but she's also got a serious proposition for "Dancing with the Stars!"
