"Rowdy" Ronda Rousey may be the UFC Women's Bantamweight Champion, but he is also a big wrestling fan. Her nickname was adopted from the late great "Rowdy" Roddy Piper as he gave her permission to use it, as per MMA News. Along with Marina Shafir, Jessamyn Duke and Shayna Baszler, they are known as "The Four Horsewomen" of MMA, based from the wrestling stable "The Four Horsemen."

She first appeared at SummerSlam 2014 in Los Angeles, Calif., with the other "Horsewomen" and was interviewed by WWE.com about her being a fan of the business. "I'm a huge fan and this is the one day of the year I happen to be able to go walk around and meet people. It's become our house activity to sit down and watch wrestling. It's been such a crazy year with all the fights and the movies. It's really rare for us all to have time to go do something together," Rousey said.

The 28-year-old was also asked if she will ever be inside a WWE ring saying, "You never know. I have a lot of crazy opportunities on my plate right now. I'm going to try to do as many as possible at the right time or at the best time."

And the best time was at WrestleMania 31 where she entered the ring for the first time to help Dwayne "The Rock" Johnson confront "The Authority," Triple H and Stephanie McMahon. It was one of the best moments of the year, with Ronda giving Triple H a judo toss and teasing an armbar on Stephanie.

The word coming out of the event is she will team up with The Rock to go up against the WWE's power couple at next year's WrestleMania 32 in Dallas. But it looks like it's not going to happen as Ronda confirmed in a fan Q&A in Australia for UFC 193 that she will be filming "Mile 22" with Mark Wahlberg and Iko Uwais in Jakarta, Indonesia in March 2016, according to MMA Mania.

"I would love to, but I'm going to be in Jakarta filming my movie. If I was really going to be there, would you want to know, or would you want to be surprised? I think a real wrestling fan would want to be surprised," the most dangerous unarmed woman on the planet said via FOX Sports.

There is still a possibility of her flying out of Indonesia just to appear at Wrestlemania32 in a non-wrestling role as this year's appearance was not expected at all. UFC President Dana White is very supportive of his superstar crossing over to WWE.

"The thing she did with WWE was cool, it was cool. She did a great job, I thought it was awesome, but believe me when I tell you she's got a lot of [expletive] to do. She's pretty busy," White said.
