UFC bantamweight champion Ronda Rousey interviewed WWE superstar Roman Reigns on SI Now before his match against Brock Lesnar at Wrestlemania 31.

"I think it's important to do both," Reigns said when asked by Rousey if it was more important to take Lesnar's WWE title or steal the show. "If I can steal the show, then I'm definitely going to win the WWE world heavyweight championship. So if we can somehow combine them both, that would be awesome."

Rousey and Reigns also discussed his willingness to do a "hair versus hair" match against Rousey, his influences for the Superman punch, hand-wrapping and more.
