Dwayne Johnson Says He's 'So Proud' of Kevin Hart at 'Jumanji: The Next Level' Premiere (Exclusive)

The actors and besties emotionally opened up to ET on the carpet at the premiere of their new movie on Monday.

Kevin Hart will soon be immortalized in cement as part of the legendary footprint ceremony at the TCL Chinese Theatre, and his longtime friend and collaborator, Dwayne Johnson, couldn't be happier for him.

The besties, and frequent co-stars, walked the star-studded blue carpet outside the famed Hollywood theater on Monday night for the premiere of their new film, Jumanji: The Next Level, and the pair stopped to talk with ET's Kevin Frazier about Hart's big honor.

"I'm very excited man! It's a big deal," Hart said of the ceremony. 

The honor was already bestowed upon Johnson back in 2015, and Hart jokingly said that the action star brought that up almost immediately.

"He already did remind me. I called him, 'Hey man, it's happening! It's happening DJ! Hand and foot print ceremony,' [he goes], 'Yeah, I did it,''' Hart joked.

While the pair love to mess with one another, the love and respect is evident in their long and enduring friendship, and Johnson explained how much he's looking forward to Hart's ceremony.

"I'm so happy and so proud of him," Johnson shared. "I have the privilege of speaking on his behalf tomorrow and I can't wait."

The actor also said that it's because of his own experience with having his hand prints and footprints cast in cement that he knows how much it'll mean for Hart.

"I did have the honor of having it done and, not to mess with him, but I know how cool it is and I'm so happy that he's experiencing it," Johnson shared. "This is a great Christmas. It's a great holiday… I'm so happy to celebrate my guy."

The pair have been promoting the upcoming action adventure for quite some time, although Hart was forced to step back when he was involved in a near-fatal car accident in September, and required emergency surgery. A source told ET that Hart fractured his spine in three places and had to undergo major surgery. He was released 10 days after the crash.

After a period of physical therapy and physical rehabilitation, Hart was soon back on the promotional tour with Johnson and their fellow co-stars.

It's been an emotional ride, and the experience of getting to spend time together throughout the course of filming and promoting the movie is one Johnson said he's going to miss.

"I've had the greatest time. Truly. The most joyful time with Kevin and the cast, traveling," Johnson shared. "It helps we made a great movie, you know, and my guy here, the times we've had. The interviews…. [it's been] epic. Everything's been epic."

"It's been unbelievable," Hart said, echoing Johnson's sentiments. "At the end of the day, you're promoting something that you're proud of, that you're happy about, and we both understand how fortunate we are to be in this particular franchise. To be able to discuss it. It's been one for the record books."

While chatting with the duo, two of their co-stars -- Danny DeVito and Danny Glover -- adorably crashed the interview to share some hugs and some laughs, and DeVito weighed in on getting to work alongside his co-stars in the hotly anticipated sequel.

"We had a great time man. We had a great time. These guys are the best," DeVito gushed. "They're family. They take care of us."

Putting his arm around DeVito and standing alongside Glover and Johnson, Hart excitedly added, "See this right here? Look at how we're standing. Somebody take a family portrait because that's what this is."
