Brody Jenner, fiancée Tia Blanco welcome first child together: 'Incredibly in love'

Brody Jenner and fiancée Tiarah "Tia" Blanco are officially parents.

Their daughter, Honey Raye Jenner, was born July 29, the couple announced on Instagram Thursday.

"Momma and baby are in perfect health. We are so incredibly in love and have been cherishing this precious time together as a family," the caption of the joint Instagram post reads. "We want to thank everyone for all the love and support."

In the birth announcement on Instagram, they shared a clip from Honey Raye's water birth and revealed they compiled more videos from Blanco's pregnancy journey, including her home birth, proposal and baby shower, in a YouTube video.

Honey Raye is Jenner and Blanco's first child together. The couple became engaged during their baby shower earlier this summer.

Brody Jenner, who once dated Lauren Conrad and appeared on the MTV reality show "The Hills" in the late 2000s, is one of Caitlyn Jenner's two sons with actress and Emmy-winning songwriter Linda Thompson.

Thompson shared that she was there to witness her granddaughter's birth.

"I feel so extraordinarily blessed, privileged and grateful to them that I was asked to be there for the labor and delivery," Thompson wrote in the caption of her own Instagram post about her granddaughter's birth. "Tia is not only a champion surfer, she is a champion of life! And Brody was the absolute perfect supportive and loving partner to her during this intense, spiritual, powerful & beautiful time."

Brody Jenner vows to do 'things differently' than father Caitlyn Jenner

In the nearly 13-minute, reality TV-style YouTube video, Jenner and Blanco share their family and friends' reactions to their engagement and pregnancy as well as their own thoughts on parenthood.

"I think that what I'm most excited about is doing things differently than my father did," Jenner said in a voiceover that accompanied clips from Blanco's pregnancy.

He said that growing up, he didn't have "the greatest relationship" with his father, Caitlyn, who "wasn't really around for me." That's why he wants to do "the exact opposite, being the absolute best father I could possibly be."

Caitlyn Jenner appears briefly in the video as a guest at the baby shower.

As for the details of Blanco's pregnancy, the 26-year-old went into labor "one week and one day after her due date," Jenner revealed in the YouTube video.

Blanco recalled reaching "a point of desperation" as it grew dark outside. At last, she gave birth 19 hours after she started going into labor.
