Jennifer Lopez Dishes on Ben Affleck's Super Bowl Commercial and What Fans Didn't See (Exclusive)

The triple-threat star dishes to ET about her husband's hilarious commercial with Matt Damon, Tom Brady and more.

Jennifer Lopez is supporting her "genius" husband, Ben Affleck.

At the premiere of This Is Me... Now: A Love Story at the Dolby Theater in Hollywood, California, on Tuesday, Lopez gave fans a behind-the-scenes glimpse at Affleck's viral Super Bowl spot for Dunkin' while speaking with ET's Kevin Frazier.

In the commercial, Affleck is joined by his famous friends, Matt Damon, Tom Brady and Jack Harlow, as they form a new group called The DunKings. The group goes into the studio to show off their musical skills to Lopez, and see if she'll add them to her album.

Lopez revealed to ET that Affleck orchestrated the entire collaboration. "That's the genius that is Ben Affleck," Lopez mused. "It has nothing to do with me. I just did whatever he asked me to do, I'm like, 'Yeah, sure, I'll be there.'"

Lopez also confirmed that Affleck was indeed singing and dancing in the ad. "He was doing all of the things," she noted. She also teased some amusing outtakes from the shoot, highlighting the fun atmosphere on set with Damon, Brady, and the rest of the crew.

One memorable moment in the commercial has Lopez unimpressed with the musical talents of Affleck and his friends -- but she still asks Brady to stay behind. 

When asked about Affleck's reaction to her line about the NFL legend, Lopez exclaimed, "He made that line up! Yes, he did."

On Tuesday's episode of The Late Show With Stephen Colbert, Damon also shared his stories from the Super Bowl commercial with Affleck. Midway through the interview, Colbert surprised Damon by unveiling the iconic pink-and-orange DunKings tracksuits, a hot commodity that swiftly sold out online. With a mischievous grin, Colbert presented Damon with a DunKings jacket, expressing his desire to join the band.

"May I be a DunKing?" Colbert quipped, handing Damon the jacket.

Damon, ever the good sport, welcomed Colbert into the fold with open arms. "The only qualification for being a DunKing is the willingness to put this on," he quipped, gesturing to the jacket. "So you're in the band. You made it."

Colbert couldn't help but joke about the snug fit of the tracksuit. "It's a completely sealed plastic bag," he remarked as he struggled to don the outerwear over his suit. "I feel like I'm trying to make weight for the wrestling team."

Damon, quick with a witty retort, assured Colbert that the jacket was perfect for dancing, eliciting laughter from the audience.

Earlier in the interview, Damon revealed that the Super Bowl ad was the brainchild of his best friend, Affleck. "That is clearly not my idea," Damon chuckled. "But we had a lot of fun doing it, though."

Colbert particularly enjoyed a scene in the commercial where Damon humorously tells Affleck, "Remember when I told you I would do anything for you? This is anything."

"I actually said that to him while we were filming, and he just left it in," Damon explained. "However much time we have on this beautiful planet, he's got no more chip with me."

While Affleck and the DunKings are going viral, Lopez is excited to soon share with the world her musical experience, This Is Me…now: A Love Story, which will premiere Feb. 16 on Prime Video.
