Last week, reality star Tia Booth announced the birth of her second baby, a girl, with her husband Taylor Mock. She didn’t reveal her newborn’s name at the time, sharing that she was waiting to get family pictures taken in her baby’s new room. Now, the Bachelor alum has announced her daughter’s moniker.

Tia shared a series of images of her and Taylor’s newborn, with some images featuring members of their family. The couple chose to name their daughter Miller Jean. “Meet Miller. Miller Jean Mock.” The couple opted not to continue a naming pattern with their daughter, as Tia, Taylor, and their first baby all have “T” monikers.

Miller joins the family with the couple’s first baby, a son named Tatum. Tia and Taylor welcomed Tatum Booth Mock in December 2022. For her son’s birthday last year, the reality star gushed on Instagram, “The light of my life is TWO!! I can’t believe I get to be your mama.” In Miller’s announcement post, Tatum was featured in some images with her new baby sister, with one picture showing him holding a stuffed rabbit near her. Fellow Bachelor alum Adam Gottschalk referenced the moment in the comments of Tia’s post writing, “I can already hear behind the camera ‘Tatum be GENTLE’ ❤️❤️❤️.”

Tia first met Taylor at a party in January 2021 right before she was preparing to film the seventh season of Bachelor in Paradise. After returning home to Nashville after not finding love on the reality series, the couple went on their first date in the summer of 2021. The following year in April 2022, Taylor proposed to Tia at a Bachelor Live show in Atlanta. The couple went on to tie the knot in November 2023, nearly one year after welcoming Tatum.

Congratulations again to Tia and Taylor on the arrival of baby Miller!
