Chip Gaines confessed to flirting with Martha Stewart in 2019.

On Tuesday, Chip and Joanna Gaines appeared on "The Tonight Show Starring Jimmy Fallon," discussing their love story, their Magnolia Network, and Joanna's recent memoir, "The Stories We Tell."

The trio also chatted about Taylor Swift, as the "Fixer Upper" stars shared that they believed they made eye contact with the singer at the 2019 Time 100 Gala, which Fallon also attended.

As they reflected on the event, the Gaineses shared that they were overwhelmed by all of the celebrities who were in attendance.

"Everyone was mingling," Joanna said. "There was The Rock, Martha Stewart. We were in awe. We were two kids from Waco, Texas."

And at the mention of Stewart, Chip piped in to share he made an advance on the mogul during the event.

"I flirted with Martha Stewart in an aggressive — in a very real way," Chip said to laughter from the audience.

"Yeah, you did," Joanna confirmed.

"I told her, 'If anything ever happens to Jo, you better watch your DMs,'" Chip continued.

Chip and Joanna have been married for nearly 20 years, as they tied the knot in 2003 after meeting at Joanna's father's auto shop.

They share five children and have built the Magnolia empire together, launching the Magnolia Network after the success of "Fixer Upper" and turning Waco into a tourist destination.

Chip actually announced they would be launching the network during an appearance on Fallon's show in 2019, which he said on Tuesday he was not supposed to do.

"Right before we came out, they said, 'Don't mention it, Chip,'" Joanna said.

"And I was like, 'Well, I've got to announce the network now,'" Chip joked. "We were nervous that we were gonna go offstage to handcuffs."
