Jimmy Fallon and Dwayne Johnson with the military family on The Tonight Show NBC

Jimmy Fallon was in tears as he and Dwayne "The Rock" Johnson reunited a military family for Christmas on Friday's episode of The Tonight Show. As the show was about to conclude, the Fast & Furious star, who is a huge supporter of the US troops, said he would like to give back "to a military family".

"There is one more thing I would like to do before I leave tonight, Jimmy [Fallon]," the 44-year-old actor said. (Via The Daily Mail) "I'd like to give back to a military family who's in the audience."

Next, the Baywatch actor and the 42-year-old comedian looked around for the said military family and ended up backstage, where the duo found the talk show's producer Karina Kabalan, who was confused when Johnson gave her a hug and told her, "I hear you're a producer of this show and you're an army vet."

"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," Johnson said,

"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."

As Kabalan started to tear up, her husband sneaked up behind her dressed in his military uniform.

Johnson then told her: "And we wanted to bring your husband home for the holidays. Turn around and hug your husband."

Fallon was seen wiping his eyes as the couple reunited for the holidays. "Oh man, I'm losing it right now," Fallon said.

Fallon later took to Twitter and wrote, "I can't believe we pulled that off. I lost it."
