Diamond Dallas Page Says Cody Rhodes' WrestleMania Match Will Be 'Emotional'

Diamond Dallas Page says Dusty Rhodes would have been overjoyed to watch his son, Cody, in the main event at WrestleMania 39 ... telling TMZ Sports "he would be walking on clouds."

Page -- who mentored his late best friend's son since he was a kid -- told us Cody's heavyweight championship match against Roman Reigns on Sunday, April 2 is the culmination of a journey, and a moment the Rhodes family can savor forever.

DDP explained the fact that Cody left WWE in May 2016 when he felt the company didn't believe in him, and then came back to have a monumental moment like the main event at WM 39 is proof of what can happen when people believe in themselves.

Cody -- a former WWE intercontinental champion -- joined All Elite Wrestling (AEW), where he spent six years competing before rejoining the WWE last April at WrestleMania 38.

Now, he has the opportunity to end Roman's 900+ day streak as Universal Champion.

DDP says he was honored to be one of Dusty's closest friends ... and he knows that after all the years of hard work and dedication the Rhodes family put into the craft, it will be "really emotional" to watch Cody enter the squared-circle.

We also spoke to Cody recently, and the 2023 Royal Rumble winner admits defeating Roman Reigns at WM would be a "tall task" -- but reassured everyone he's up to the challenge.

"If you're in the spot you want to make sure you get the job done," said Rhodes, the half-brother of Dustin, professionally known as Goldust during his WWE career.
