You probably grew up watching them. The denim hats, the "Go home, Roger!" screams, and that uncanny ability to finish each other's sentences. For most of us, Tia and Tamera Mowry aren't just actresses—they are the blueprint for sisterhood. But lately, the internet has been buzzing with a weirdly specific question: "Who is the other Tia and Tamera sister?"
Let's get the record straight immediately. There isn't a third sister.
Honestly, it’s kinda funny how these rumors start. Maybe it's because they have two brothers who are also in the industry, or perhaps people are just manifesting a Twitches style triplet reveal. But if you’re looking for a secret Mowry sister hidden in the wings of a Hollywood stage, you’re going to be looking for a long time.
The Mowry Siblings: It’s a Brother Thing
The Mowry family is tight. Like, military-family tight. Their parents, Darlene and Timothy, were both U.S. Army sergeants, which means the kids grew up with a lot of discipline and a whole lot of moving around. While there is no other "Tia and Tamera sister," there are two very talented brothers who complete the squad.
Tahj Mowry is the one most people recognize. If you didn't watch Smart Guy, were you even alive in the late 90s? Tahj played T.J. Henderson, the kid genius who jumped from fourth grade to high school. He’s been a staple on TV for decades, from Full House (remember Teddy?) to his long run on Baby Daddy. He and the twins are incredibly close, often showing up on each other’s social feeds for birthday tributes that’ll make you want to call your own siblings.
Then there’s Tavior Mowry.

Tavior is the youngest of the four. He didn't take the acting route like the other three, which might be why some fans feel like there’s a "missing" piece of the puzzle. He played football at UC Davis and eventually pivoted into the music world. He’s a producer and a musician, carving out a path that’s entirely his own, away from the sitcom cameras.
Why the "Third Sister" Rumor Won't Die
Why do people keep searching for a Tia and Tamera sister?
Sometimes, fans confuse their Sister, Sister co-stars for real-life family. For a while, people thought Bianca Lawson (who played Rhonda on the show) or even Alexis Fields (Diavian) might be related to them. They aren't. They’re just great actresses who matched the energy of the twins so well that it felt like family.
There’s also the "cousin" factor. The Mowrys have a huge extended family, and they’ve mentioned cousins in various interviews. In late 2025, Tia and Tamera even did a partnership with HomeGoods where they talked about their "cousins' holiday tradition." If you catch a glimpse of a family photo with a bunch of women who look vaguely like the twins, it’s easy to let your brain fill in the gaps and assume there's another sister.
The Truth About the "Rift"
Being a sister is hard. Being a twin is harder. Being a twin in the public eye for thirty years? That’s a whole different level of pressure.

Lately, the headlines haven't been about a secret sister, but about the distance between the two we actually have. In her reality series, Tia Mowry: My Next Act, Tia got really vulnerable. She mentioned feeling like she and Tamera weren't as close as they used to be. She used the word "accessible," saying she wished she could just pick up the phone and call Tamera like she used to.
People freaked out.
The internet did what it does best: it assumed there was a massive feud. Rumors flew that Tamera’s more conservative lifestyle or Tia’s divorce from Cory Hardrict had caused a permanent break.
Tia eventually had to step in and clarify. She basically told everyone to calm down. There’s no "rift"—there’s just life. Tamera lives in Northern California with her husband Adam Housley and their two kids, Ariah and Aden. Tia is in Los Angeles, navigating life as a single mom to Cree and Cairo.
"We've all grown up," Tia explained in a December 2025 interview. "We have our own families. Of course there's space." They actually made a pact to talk every single Sunday to make sure they don't drift too far apart. It’s not a Hollywood drama; it’s just the reality of being 47 years old with separate lives.

What You Should Actually Know About the Mowry Bond
If you're looking for the "real" story behind the Tia and Tamera sister dynamic, it’s less about secret siblings and more about the insane work ethic their mom, Darlene, instilled in them.
- The 1-Month Rule: When the twins were 12, they convinced their mom to move to LA. She gave them exactly one month to land a job. If they didn't, they were heading back to Texas.
- The "Voices" Era: Before Sister, Sister, they were in an R&B group called Voices. They even danced for MC Hammer.
- Identical vs. Fraternal: There’s a long-running Reddit conspiracy that they are fraternal because they look different now. Nope. They took a DNA test on their old reality show. They are 100% identical.
Actionable Takeaways for Fans
If you’ve been following the Mowry journey, don't get caught up in the "secret sister" clickbait. Instead, look at how they handle their actual family dynamics:
- Respect the Space: Just because you aren't posting photos together every day doesn't mean the love isn't there. Adult siblings often have to schedule their "Sunday pacts."
- Support Individual Paths: Tavior Mowry proves you don't have to do exactly what your famous siblings do to be successful and loved within the family.
- Check the Source: Most "secret sibling" rumors come from people misidentifying cousins or old co-stars in blurry Instagram stories.
The Mowry family remains one of the most stable and transparent families in Hollywood. While there isn't a secret Tia and Tamera sister, the four siblings they do have—Tia, Tamera, Tahj, and Tavior—offer more than enough talent and heart to keep us watching.
To stay updated on the Mowry family, the best move is to follow their individual ventures, like Tia’s Quick Fix projects or Tamera’s work with the Hallmark Channel, rather than waiting for a family reunion that looks like 1994. Life moves on, and so have they.
