Tia Mowry recalls babysitting Mary-Kate and Ashley Olsen with Tamera

There was double trouble behind the scenes of the Full House set thanks to Tia Mowry and her twin sister, Tamera Mowry-Housley.

In an Instagram post the Family Reunion star shared on Tuesday, Mowry recalled the long journey the siblings traveled to get their Sister, Sister sitcom off the ground, which began when their brother Tahj Mowry appeared on Full House as Michelle Tanner’s friend, Teddy. The sisters would tag along with their mother to the ’90s sitcom set, which led to the twins being asked to babysit stars Mary-Kate and Ashley Olsen, who were seven years younger.

“They had us babysit Mary Kate and Ashley on set,” Tia, 46, wrote in the Instagram post. “The crew would have us play with Mary Kate and Ashley between takes.”

The actress noted that those watching seemed to enjoy seeing the two sets of twins interact with one another. “Everyone thought it was the cutest thing,” she continued. “Twin girls watching over twin girls.”

The Mowry sisters would go on to lead their own beloved sitcom, which Mowry credited to Suzanne de Passe — chairwoman of de Passe Jones Entertainment Group — introducing them to Kim Bass, the creator of Sister, Sister. She shared that there were several ups and downs during the show’s early production, revealing that, at first, the show wasn’t picked up for the fall lineup. When it was picked up for the midseason lineup, it was canceled after one season.  

But then Warner Bros. picked up the series and gave the girls a 100-episode guarantee, which Mowry saw as proof that everything was meant to be.

“A lot of people think our journey to Sister, Sister was easy… but trust me, it was far from it,” she wrote in the caption. “As kids, we faced a lot of heartache and uncertainty. But every challenge taught me something. It shaped my faith, my resilience, and prepared me for everything that came after. I wouldn’t change a thing.”

Much like how Mary-Kate and Ashley expanded their brand after Full House, the Mowry sisters followed a similar path after starring on Sister, Sister. They starred in various projects together, including the 2000 movie Seventeen Again, the Disney Channel Original Movie Twitches (2005), and its 2007 sequel, Twitches Too. In 2011, the sisters even starred in a reality series together titled Tia & Tamera, which followed the day-to-day lives of the twins and ran for three seasons. 

Although the sisters haven’t been in a project together in a while, Mowry-Housley has said she would be up for a reunion in a Twitches threequel, even pitching musical duo sisters Chloe and Halle Bailey to star alongside her and Mowry. “I love those girls. I think that would be sick,” she told PEOPLE in 2020. “All we need is Disney to be down. It could be a fun Disney+ kind of movie.”

The sister made headlines last year while Mowry was promoting her We TV reality show, Tia Mowry: My Next Act. Fans went into a tizzy when a preview for the show included a clip of Mowry saying she wished she was “still close” with her twin

Mowry shut down assumptions of an estrangement, clarifying that the comments pertained to physical distance. Mowry resides in Los Angeles, while Mowry-Housley resides up north in Napa, Calif.

“I love my sister very much. She loves me very much, We have a closeness and a beautiful connection,” Mowry told Us Weekly. “As we grow up, we all start our own families and their children need to lean on them. We begin to take on new roles and responsibilities within our lives. That is what that was all about.”

“In these transitions in life, sometimes you just want a hug and you just want someone to be as accessible as they used to be, and that is not the case,” she added. “It’s called life.”
