Jennifer Lopez and Ben Affleck were "emotional" and "cried to each other" a witness recalled as they recited their vows while getting married after midnight in Las Vegas, Nevada, on Sunday.

Kenosha Portis, an employee working at A Little White Wedding Chapel when the couple finally tied the knot, told Good Morning America on Tuesday that Ben and Jen were really "sweet" newlyweds.

"It was so exciting," Portis said. "I mean, we were getting ready to close, and we had a special guest arrive as a walk-in."

She recalled: "I started shaking a little bit. Like, ‘This is Jennifer Lopez we are getting ready to marry!'"

The couple announced their marriage via newsletter on Jennifer’s website Sunday afternoon: "We did it. Love is beautiful. Love is kind. And it turns out love is patient. Twenty years patient."

"As they were reading each other’s vows, they were very sweet, they both were emotional," Portis said. "They cried to each other. The kids were right there behind them."

Their last-minute nuptials were a surprise to many as they said "I do" with her child, Emme, and his youngest daughter, Seraphina, in attendance.

"She had on a nice, elegant, beige, lacy type dress," Portis said of JLo's gown from the Zuhair Murad Bridal Spring Summer 2023 Collection. "It had a train on it. The veil was beautiful."

"Everything was very sleek and beautiful. She was stunning. She had a beautiful bouquet, white bouquet, that she had, and he had a boutonniere as well that matches that."

The newlyweds now have five children in total. Lopez has 14-year-old twins Max and Emme with ex-husband Marc Anthony, and Affleck shares three kids — Violet, 16, Seraphina, 13, and Sam, 10 — with his ex-wife, Jennifer Garner.

Garner reportedly didn’t know about the Las Vegas nuptials, and was in Lake Tahoe while her ex was walking down the aisle.

"Ben did tell Jen about the wedding, but I’m told that it was only Friday at the earliest," the source told The Post.

JENNIFER LOPEZ, BEN AFFLECK'S 20-YEAR JOURNEY TO MARRIAGE AND HAPPILY EVER AFTER

The "Maid in Manhattan" actress celebrated her wedding day with her new husband on a private plane back to Los Angeles, where the couple sipped on Diet Coke and ate pizza, according to Page Six.

She reportedly felt pressure to get down the altar and "rushed" to get married after the couple received a marriage license on Saturday.

"[Lopez] has been ready to get married since the night that Ben proposed. She wanted to lock this down and remove any chance for cold feet ASAP," a source said.

A second wedding is already in the works now that the couple is married, as an insider revealed to People magazine that Bennifer is planning a "bigger party so they can celebrate with family and friends."

In addition, "They don't have a honeymoon planned yet. Jennifer says that every day with Ben is a honeymoon."

Lopez and Affleck are reportedly hosting a "massive bash" at a home he owns in Riceboro, Georgia, according to TMZ.

The compound has three separate structures and is roughly one hour outside of Savannah on the exclusive Hampton Island Preserve.

Affleck reportedly purchased the property for $7 million in 2003 when he was first engaged to Lopez. 

Ben and Jen were first engaged in 2002, and had plans to marry in September 2003, but postponed the wedding and eventually called off their relationship by January 2004. They rekindled their romance in April 2021 and announced their engagement earlier this year after he proposed while she was in the bathtub.

Court documents show the "Jenny from the Block" singer, listed as "Party 2," requested a "new name" on their marriage certificate filing, which was first received on Saturday, July 16 at the Clark County Clerk's Office.

The "Marry Me" star previously changed her name when she was married to singer Marc Anthony. Nearly six months after their divorce was finalized in 2014 — and three years after they had separated — Lopez dropped his surname, Muniz.

She was also previously married to back up dancer Cris Judd from 2001-03, and had a one-year marriage to Ojani Noa, which began in 1997 and ended in 1998.

"When love is real, the only thing that matters in marriage is one another and the promise we make to love, care, understand, be patient, loving and good to one another," she wrote in her newsletter. "We had that. And so much more. Best night of our lives."

"They were right when they said, ‘all you need is love.’ We are so grateful to have that in abundance, a new wonderful family of five amazing children and a life that we have never had more reason to look forward to.

"Stick around long enough and maybe you’ll find the best moment of your life in a drive through in Las Vegas at twelve thirty in the morning in the tunnel of love drive through, with your kids and the one you’ll spend forever with. Love is a great thing, maybe the best of things-and worth waiting for."

She signed off her post: "With love, Mrs. Jennifer Lynn Affleck."
