Tia Mowry Reunites with Her 'Grandpa' from 'Seventeen Again' : 'This Dude Doesn't Age'

Tia Mowry and Mark Taylor had a sweet reunion 21 years after they shot the beloved family film Seventeen Again.

Tia, 43, posted an ageless selfie on Thursday with Taylor, 44, who once played her grandfather in the 2000 film.

The actress was in glam and a red holiday sweater while her former costar wore a grey collarless button-down shirt.

"Talk about a #tbt! Who remembers 17 again?" Tia captioned the post. The actress starred as Sydney and Taylor played a young version of Grandpa Gene, while her twin Tamera Mowry played the young version of Grandma Cat.

She then revealed the reunion is because they are "back together working on a movie for @lifetimetv! 😄."

In addition to Tamera, also 43, Tia's sibling Tahj Mowry appeared in the movie. Tahj starred as Tia's brother Willie, who accidentally spilled an age reverse potion on Grandpa Gene's bar of soap.

Tia joked in her caption, "I think @therealmarktaylor7 must have gotten a hand on that magical soap! This dude doesn't age!"

Her hashtags, "Summer Of Santas" and "A Very Vintage Christmas" hinted that she and Taylor will be in a Hallmark holiday movie.

"Yaaaay!!!!! Have fun!! 😍" Tamera commented.

Michelle Trachtenberg commented, "OMG! I did a movie also called 17 again" referring to the 2009 film opposite Zac Efron. She added, "But this one seems way cooler! 😻💋."
