Nash Grier's mother-in-law has been reported missing.

The YouTuber's wife Taylor Giavasis, 28, shared Aug. 20 that her mother, Nikki Giavasis, 48, has been missing since Aug. 18 and was last seen in Ft. Lauderdale, Fla.

Along with noting her mom's distinguishable feature of a "tattoo of angel wings with the names Mal and Noa on arm," Taylor shared, "Nikki’s family is urgently seeking any information regarding her whereabouts."

The missing persons poster asked that if anyone has seen Nikki—who was last seen wearing a dress and has brown eyes and long brown hair—to contact the Fort Lauderdale Police Department.

The former Vine star, 27, shares kids Malakai, 5, and Noa, 3, with Taylor, who he began dating in 2015. After getting engaged in 2019, the couple tied the knot in an intimate ceremony in December 2024—where Nikki was in attendance.

At the time, Nash shared photos from their special day and added the caption, "Romanticizing life,” with Nikki adding a sweet note, commenting, "So happy I was there to witness how special the first two are!! The most beautiful love and Noa and Malakai were so happy!"

While many know Nash as a former MagCon member alongside Cameron Dallas and others, the social media personality recently shared that he's grown up a lot since becoming a father.

"27 today, a lot has changed since I became a father 5 years ago including my perception of time. The years have been flying by lately," he wrote in December 2024, days after the wedding. "I take lots of pictures and videos and try my best to savor every moment."

Nash also noted how as he's gotten older, he's learned what matters most in life, as shown by his many posts spending time in nature and playing outside with his kids.

"Everyday I become more and more grateful for the simple pleasures of life like the weather, home cooked meals, reading with the kids, riding a bike, fresh fruit/vegetables, good conversations, long runs, healthy soil, raising chickens, playing in the snow," he continued. “The list goes on and on and I’m looking forward to another year of adding to it."
