Jennifer Lopez experienced “a little PTSD” before marrying Ben Affleck.

Because the couple’s previous engagement “fell apart,” the singer kept asking herself whether their second attempt at tying the knot was “really happening,” she explained to Jimmy Kimmel Wednesday.

“We were so happy and, of course, it was happening, but the wedding was so stressful,” the Grammy winner, 53, recalled.

Lopez noted that their July 2022 Las Vegas wedding was Affleck’s idea.

“One day, Ben just said, ‘F–k it, let’s just go to Vegas and get married tonight,’” the dancer said. “He said, ‘Go to rehearsal. When you get back here, I’ll have everything set up.’”

One month after the pair tied the knot in Sin City, they went on to wed again in front of family and friends in Georgia.

Lopez and the Oscar winner, 50, were previously engaged from 2002 to 2004. The “Gigli” co-stars rekindled their romance in 2021.

By that time, the songwriter was fresh off a broken engagement from Alex Rodriguez. Lopez was previously married to Marc Antony, with whom she shares twins Emme and Maximilian, 14.

As for Affleck, the “Tender Bar” star wed Jennifer Garner in 2005. Prior to their 2015 split, the exes welcomed Violet, 17, Seraphina, 14, and Samuel, 10.

After Lopez and the actor got back together, Affleck proposed with a green diamond ring.

“He had to ask me again,” Lopez said on “Jimmy Kimmel Live!” of the April 2022 proposal, which took place while she was in the bathtub. “I didn’t have that [ring] anymore.”

Affleck gushed to Vogue about their second-chance romance in November 2022, calling Lopez “exactly the person” he remembers “from 20 years ago.”

The Golden Globe winner winner added, “Maybe she sees all the changes she’s made, whereas when I see her, mostly I just see someone who has retained, against the odds, the thing about her that always made her the most incredible to me.”
