Jennifer Lopez shared a sweet video from the twins' 16th birthday trip

Jennifer Lopez's kids, Emme and Max, don’t spend a lot of time in the public eye, but their mom sometimes shares snippets of their lives with her hundreds of millions of Instagram followers each year on their birthday, Feb. 22.

For their special 16th birthday, Lopez posted a video of the kids' birthday trip to Japan.

"I've never seen Max so excited," Lopez said to Emme, who responded, "I've never seen myself so excited."

The video is a montage of all of their adventures in Asia, including eating traditional foods, cuddling piglets, pounding mochi, enjoying a tea ceremony, experiencing a light exhibit and sharing two birthday cakes connected by a "hashi," or bridge.

The pop star layered her song, "Hummingbird," over the images.

At the end of the video, Lopez wrote, "Happy Birthday to my coconuts. I love you." She often uses "coconuts" as a pet name for her twins.

She splits co-parenting duties with her ex-husband, singer Marc Anthony. Together with her husband, Ben Affleck, she is helping to raise stepchildren Violet, Seraphina and Samuel, whom Affleck shares with his ex-wife, Jennifer Garner.

Lopez appeared on TODAY on Feb. 15 to discuss her new album “This Is Me... Now,” as well as her Amazon original film “This Is Me... Now: A Love Story.”

"And by the way, your kids are turning 16," Hoda Kotb said.

"Isn't it crazy, they're 16," Lopez said.

Here’s everything you need to know about Lopez’s “coconuts.”

Emme Maribel Muñiz

From giving mom the death stare for filming at a SZA concert to sharing the stage at the Super Bowl halftime show in 2020, Emme isn't afraid to let her personality show.

Does Emme have a singing career in the future? It's quite possible. The teenager, who Lopez has referred to using gender-neutral pronouns, has continued to sing alongside their mother. In 2022, Emme harmonized with Lopez to Christina Perri’s “A Thousand Years” at the Los Angeles Dodgers Foundation’s Blue Diamond Gala.

"This is a very special occasion," Lopez joked at the event, because Emme is "very, very busy and booked and pricey. They cost me when they come out, but they’re worth every single penny because they’re my favorite duet partner of all time. So if you would indulge me."

Emme is also a published author of the inspirational picture book "Lord Help Me" about the everyday power of prayer.

Maximilian "Max" David Muñiz

Max seems to be a socially conscious teenager. Deeply affected by George Floyd's murder, Max urged Lopez and her then-fiancé Alex Rodriguez to attend a protest. The kids helped the pair make signs that read, "Black Lives Matter" and "Let's Get Loud for Black Lives Matter."

“He wanted me to make sure I realized that I had power and that I should use it, and I thought that was very insightful," Lopez shared with Elle magazine. "It was one of those parenting moments when you’re like, Oh, maybe I’m raising a conscientious, kind, loving kid here."

Even at age 11, Max asked his mom some insightful questions on her YouTube channel. He wanted to know what she was like at his age, questioned her about her first crush, tried to make her admit that "math is useless" and asked if being a mom was different than she expected. In the casual AMA, Lopez said her favorite thing about Max was his sense of humor, his incredible vocabulary and his "big heart."

Overall, Max tends to keep a lower profile than his sister, but he did make his acting debut in "Marry Me," the rom-com his mother headlined in 2022.
