It’s the time of year to spread some cheer.

And on Friday’s episode of The Tonight Show, Dwayne ‘The Rock’ Johnson and host Jimmy Fallon played Santa’s helpers as they conducted a surprise for a military family so heartwarming it brought Fallon to tears.

Towards the end of his interview, the 44-year-old actor commented about giving back to the troops before amazing the audience and reuniting a family.

‘There is one more thing I would like to do before I leave tonight, Jimmy,’ the Fast & Furious star, who’s a huge supporter of U.S. troops, teased, ‘I’d like to give back to a military family who’s in the audience.’

He and the 42-year-old comedian proceeded to search the audience for said military family – ending up backstage in the control room, where they find The Tonight Show’s producer Karina Kabalan.

‘I hear you’re a producer of this show and you’re an army vet,’ Johnson began, giving the shocked and confused producer a hug.

‘I heard that you met your husband when you were both deployed in Iraq. And your husband’s name is Todd and he is a master sergeant in the U.S. Air Force.

‘And that you guys have been living apart for the past year and a half because he’s 5,000 miles away.’

As Kabalan weeps and nods, Todd Kabalan – dressed in his distinguished uniform – sneaks up behind his wife.

Dwayne concluded, ‘What Jimmy and I wanted to do for you – we just wanted to thank you and your husband for your service and your sacrifice, and I personally heard you are the most amazing person.

‘And we wanted to bring your husband home for the holidays. Turn around and hug your husband.’

As the tearful husband and wife reunion commenced, Fallon was seen wiping his eyes and getting choked up, as he said, ‘Oh man, I’m losing it right now.’

He later took to Twitter to reiterate the sentiment, tweeting: ‘I can’t believe we pulled that off. I lost it.’

The Tonight Show Starring Jimmy Fallon airs weeknights.

Dwayne Johnson’s new film The Fate of The Furious is set to hit US theaters in April 2017.
