Brody Jenner and pregnant girlfriend Tia Blanco took to social media this weekend to share the sex of their unborn child.

The TV personality, 39, and his pro-surfer counterpart, 25, hosted a gender reveal party, which was attended by Brody's parents Caitlyn Jenner, 73, and Linda Thompson, 72.

The twosome posted the news in a joint post that appeared on each of their respective Instagram accounts.

A video from the gathering showed two people wrestling in boy and girl jumbo baby costumes, with the girl emerging as the winner to indicate the couple will have a daughter.

Brody also shared a more low-key clip of the girl 'infant' jumping around near a pool and wrote, 'Thank you to all my friends and family for making today so special. Here we go!!'

Jenner and Blanco initially revealed they are expecting a child together last month on January 1. 

They said in a joint statement: 'To start off this new year, we’d like to take this opportunity to wish all of our friends, family and followers health, happiness & an abundance of love.'

They continued: 'We truly appreciate & love you all. We are excited to share with you the blessing of a new life in the new year…Our little angel is on their way. Happy new year!'

Jenner showed Blanco, a native of Puerto Rico who was seen on ABC's The Ultimate Surfer, getting a sonogram, as The Hills: New Beginnings personality said, 'Honey, look at that little heart - what?!?'

The two were first linked last April, and confirmed their romance via social media in May.

The professional athlete told E! News last year, 'We kept our relationship pretty private at the beginning. But we're both just so in love, and it just happened naturally to share the fun things that we do and this exciting time in our life together.'

Jenner was previously wed to Kaitlynn Carter, 34, from 2018-2019, and she has since welcomed son Rowan, one, with boyfriend Kristopher Brock; the two revealed they were expecting their second child last fall.
