Talk about a Ultimate Fighting Championship (UFC) and World Wrestling Entertainment (WWE) crossover! UFC women's bantamweight champ Ronda Rousey just hopped the barricade at WrestleMania 31 tonight (Sun., March 29, 2015) and joined The Rock in the ring against Stephanie McMahon and Triple H! After some spirited trash talk between "Rowdy" and McMahon, the UFC champ hip tossed Triple H into oblivion before hitting a pseudo-armbar on McMahon. Dana White pretended he didn't know about the "WrestleMania moment" on Twitter, and everyone had a dandy ole' time!
