Tia Mowry-Hardrict Reunites with Her Sister, Sister Mom Jackée Harry in A Family Reunion Christmas

A family reunion, indeed!

In A Family Reunion Christmas, a special holiday-themed episode of Tia Mowry-Hardrict’s hit Netflix show, the actress has a sweet moment with her Sister, Sister mom, Jackée Harry.

“I can’t believe you did that to your sister … sister,” Cocoa McKellan (Mowry-Hardrict) tells Harry’s character in the special’s trailer (shared exclusively with PEOPLE) as they share a knowing look.

Harry played Mowry-Hardrict’s mom throughout the ’90s on the hit sitcom, which also starred the actress’s twin sister Tamera Mowry-Housley.

While details of the special are still tightly under wraps, Netflix has revealed the McKellans will face “ghosts of Christmas past” in the episode.

“There’s this raw, rooted, grounded authenticity that is being portrayed in the pages and the story lines,” she said. “We had 20 scripts, and I was so excited to read every single one of these scripts because of the stories that were being told.”
