However, she was dressed for in-ring action as she sported a short skirt-like kilt and a Rousey athletic top.
And that's exactly what John Cena did; he spent time during the Kickoff Show and a good chunk of the main card, sitting on the floor and watching with the rest of the fans, before running backstage to prepare for his match.
Rousey, 31, first hinted she would attend the New Orleans event with a surprise appearance at Royal Rumble in January. The four competitors would face off in the ring ahead of the bell with the heels using a few tactics from the get-go including Stephanie rushing over to yank Rousey to the mat from behind. However, there was one point where Hunter got knocked to the outside and wasn't really moving to get back in.
Rousey had plenty of opportunities to strike with her trademark armbar, applying the move to both McMahon and Triple H. She also showed off her newfound pro-wrestling prowess, repeatedly slamming McMahon. There were multiple spots that allowed her to look strong, including her picking up Triple H in a moment that had the crowd on its feet.
A little more than a year after her disappointing return to the UFC, Rousey is making a new name for herself in the WWE ring.
But when the lights went out on one more time, and the trenchcoat, hat and gloves Taker left in the ring a year ago appeared in the ring, business picked up.
WWE fans certainly seemed entertained by Ronda Rousey's big debut on "the grandest stage of them all".
