WrestleMania moments can be hard to come by but Ronda Rousey -- with The Rock by her side -- certainly made one on Sunday.

Rousey, the UFC Women's Bantamweight Champion who was spotted sitting at ringside earlier in the night, hopped over the barrier to join The Rock during a heated argument against Triple H and Stephanie McMahon. McMahon had slapped The Rock, but he was unable to retailiate and needed a woman's help.

Entering the ring to a huge ovation, Rousey refused to be intimidated by McMahon and dropped the following line:

"You need to understand something, Steph. Any ring I step into is mine. If you want me to leave, why don't you make me?"

The Rock began fighting with Triple H, leaving him stumbling as he approached Rousey, who delivered a hip toss.

McMahon then tried to slap Rousey, only for Rousey to turn the tables, put McMahon in a standing arm bar and chuck her out of the ring.

Rousey's appearance will immediately raise suspicions about her participating in a WWE match next year at WrestleMania 32. In fact, a tag team match with her and The Rock on one side, Triple H and McMahon on the other, would certainly be a headliner.

Rousey's agent, Brad Slater, told Ariel Helwani of MMAFighting.com that UFC head honcho Dana White was certainly aware of his client's participation in the event. "I've told you many times how I work with Dana [White]," Slater said. "I always, always call him and make sure he is OK with anything we ever do in movies, television and otherwise."
