‘Bachelor’ alum Tia Booth gives birth, welcomes baby boy with fiancé Taylor Mock

Tia Booth’s baby has arrived.

The “Bachelor” alum, 31, gave birth to her and her fiancé Taylor Mock’s first child, a son, on Tuesday, Dec. 6.

Taking to Instagram on Wednesday, the new mom shared an audio clip of the moment she gave birth to a baby boy who they’ve named Tatum Booth Mock at 6:13 a.m.

“Best day of our lives,” the clip was captioned. In it, Booth’s doctor could be heard congratulating her as she met her son for the first time.

Booth debuted her baby bump on Father’s Day, describing the complicated feelings she had about her pregnancy in the wake of her dad’s death.

“I’ve never felt such overwhelming sadness and pure joy at the same time,” she wrote via Instagram in June.

“It’s been difficult to be grateful for the good as if one of the most important people in my life is missing the celebration,” the “Bachelor in Paradise” alum continued. “While I wish I could tell my dad all the good news in person, it brings me peace that he knows about it long before I do.”

Booth, whose father died in February, concluded, “I have no doubt my dad had a hand in this.”

The former reality star celebrated another milestone without her parent when she got engaged in April while on stage at a live “Bachelor” event.

“Love you girl, can’t wait to do life with you,” Mock told his Instagram followers after proposing to the physical therapist.

In her own post, Booth gushed, “Never been more shocked or sure.”

The former ABC personality began dating Mock in 2021. While awaiting their little one’s arrival, Booth asked her Instagram followers to guess the sex.

“Baby boy and somehow your sweet daddy’s name is gonna be incorporated,” one social media user wrote in July, while another speculated, “I’m guessing boy — and he will have tendencies that remind you of your angel daddio.”

Later that same month, the then-pregnant star used a blue confetti cannon to announce that her son was on the way.
