She's UFC's newest rising superstar ... but Paige VanZant says there's NO WAY she'll ever step into the octogon with Ronda Rousey! VanZant appeared on "TMZ Hollywood Sports" on Tuesday -- and talked about how she made the transition from being a dancer to a legit wrecking machine. In fact, the 21-year-old says she owes a lot of her success to Rousey -- who paved the way for women to fight in the UFC. But when it comes to a possible mega-fight between the ladies, VanZant makes it very clear ... she doesn't have a deathwish.??
