You may remember Sierra Jo Dominguez as Jill Duggar and Jessa Duggar's wedding planner on 19 Kids and Counting, but she's also a devoted fundamentalist Christian and a loving mom, too! She actually has a surprising amount in common with Michelle Duggar, and is on track to have as many kids as the Duggar matriarch.

Sierra was born on Sept. 10, 1989, which means she is now 28 years old. She got married to her hubby Mark Dominguez when she was 19, and quickly decided that God would decide how many kids they have. She is now the mother of six beautiful children: Khai, Daylon, Asher, Ellyn, Edyn, and Brooks. Brooks is her youngest, and was born on Dec. 29, 2017. At the rate of six kids in nine years, Sierra could easily hit the Michelle goal of 19 kids by age 50.

But that's not where the similarities stop! Sierra also has a non-fundie past, just like Michelle. Prior to getting married and becoming super religious, Sierra came from a regular family, and celebrated Halloween, wore bikinis, and sported shorts. Now she seems to follow the same modesty standards set forth by Michelle, with just long dresses and skirts. Plus, her hubby is a pastor. She's pretty tight with the Duggar fam, so it's possible that they've influenced her. She's especially friendly with Anna and Joy-Anna.

However, she also has her differences from the Duggars. She has her babies in a hospital, for starters. She was also raised going to public school, which is actually where she met her husband. She's also very close with her non-fundie family, rather than cutting them off or trying to hide them, like Michelle's lesbian sister that we haven't seen her with in years. We'll definitely be keeping an eye on Sierra!
