15-year-old Harper stepped out for the Wicked: For Good premiere at the Lincoln Center for the Performing Arts in New York City on Monday, November 15.

She enjoyed a rare outing with her father David but didn’t have her fraternal twin brother Gideon by her side.

The teenage daughter dazzled in front of the camera in a green sequinned midi dress, while her father wore an iridescent tuxedo jacket, a white shirt, and black pants.

Last month, the family celebrated the twins’ 15th birthday on October 12.

“I really just enjoy spending time with them. They make me laugh authentically, and it’s just fun to see all the work that you’ve put into them, what they’ve become,” Neil was heard saying in an Instagram clip jointly shared by David and a fan account for the twins’ birthday.

“If you’re going to dedicate your lives to the kids and take care of them, then you get all of the wonderful things that come with kids,” David was heard saying in the same clip.

The couple became a family of two after welcoming their fraternal twins via surrogacy.

The couple revealed in the past that both of them wanted to be biological fathers, so they used both their sperm and kept the identity of the egg donor unknown.

“[There were] two different women involved. There was an egg donor, a wonderful woman who was anonymous. We took two of our best guys and implanted them into her eggs, two different eggs,” David said in the past.

The eggs were acquired through a donation bank, allowing them to research the donor’s personal and medical history.

“We inserted one of my sperm and one of David’s sperm into two eggs, with the hope that they would both take, just because we both wanted to be dads biologically, and both took, miraculously,” Neil said in a 2014 interview.

He told Oprah Winfrey that they “lucked out” after both of their embryos took.

“We really had thought it through financially, emotionally, relationship-wise. We didn’t just accidentally get pregnant. These kids come into our world with nothing but love,” he told the talk show host in 2012.

Years after gay marriage was legalized in New York, the actors tied the knot in a private ceremony in Italy in 2014, with their son and daughter by their side.

“Harper has been fussy but Gideon is the easiest baby in the world,” David said after welcoming the twins

Shortly after the twins’ birth, David spoke about how they had their own unique personalities.

“Harper has been fussy, but Gideon is the easiest baby in the world. They’re just now starting to recognize us and smile,” he told People. “That’s cleared the calendar in a good way.”

A few years later, he said on The Wendy Williams Show in 2015 that Harper’s outgoing personality is more like his.

“She’s like, ‘Hey everybody, I’m here!’” he said.

Meanwhile, Gideon seemed more like Neil because “he’s a little more heady and intellectual,” he added.

In August this year, Neil shared a post about his kids entering a big new chapter in their lives: high school.

“The kids are entering high school this year (how wait what??), and they are at last allowed to rid themselves of their Chromebook anchors and ascend to the world of the MacBook,” he said, sharing a picture of them sitting in front of their own new laptops. “Huzzah!”

Netizens commented on how the twins look all grown up.

“And I was just about going into high school when they were born,” one said. “The time how she flies.”

“Hey, I’m pretty sure they were just toddlers a few weeks ago, so there’s no way,” another wrote.

“They are both absolutely stunning! Dad and Papa have done a great job raising them!” said another.

“Omg last I saw the kids they were toddlers. Good looking family,” one recently commented
