Universal Champion Roman Reigns is set to take on WWE Champion Brock Lesnar in Wrestle Mania 38's headlining event Sunday night. Amid his success, Reigns discussed the hard work of UFC fighters Jake and Logan Paul.

The WWE superstar sat down for an exclusive interview with TMZ ahead of Wrestle Mania 38. TMZ shared bits of the interview in an article on Saturday, publicizing Reign's admiration for the Paul brothers.

“From everything that I've ever seen or heard, they put in the work,” Reigns said, all quotes courtesy of TMZ.

The WWE star mentioned the Paul brothers' lifestyles, saying that they train, eat, and “do everything that a professional boxer would do to prepare for a fight.”

“I think it would be crazy to say they're not boxers…You got to have people tuned into what you're doing” Reigns said. “And, they've done that, but they've also put in the work. Kudos to them.”

While Reigns is slated in the main event of Wrestle Mania 38, Logan Paul is set to make his Wrestle Mania debut. Paul will join The Miz in the final event of the KO Show Saturday, where they will take on Rey and Dominik Mysterio.

Both Paul brothers have made names for themselves as professional boxers in the UFC. Now, Logan looks to continue his success from internet sensation to UFC star, to WWE icon.

While there has been no official announcement, Jake could return to the UFC ring this August.
