But now, Kaitlynn has some big news of her own. It seems she has entered a brand-new chapter in her life with boyfriend Kristopher Brock, as the reality star revealed on social media that the couple have officially expanded their family.
Kaitlynn revealed that she and Kristopher Brock have welcomed their first child together.
On Oct. 6, 2021, Kaitlynn took to Instagram to share a post of her breastfeeding and announce that she and Kristopher have welcomed a baby boy.
"Our chunky little guy, Rowan Carter Brock, was born 9/30/21 at 2:53am, 8 lbs 4 oz. Everyone is happy and healthy and so in love," the reality star wrote with heart emojis.
Fellow co-stars and fans alike quickly congratulated the star on her new bundle of joy.
"Dying!!!!! So excited for you and here for you. Xxx," Whitney Port commented.
"Look at all that hair!!!! Such a cutie. Can’t wait to come snuggle him! Congratulations mama you did it!" Ashley Wahler commented.
"So beautiful you both are. Love you guys," Caroline D'Amore also commented.
Although this baby boy is Kristopher and Kaitlynn's first child together, Kristopher isn't a first-time dad. The fashion designer has a 6-year-old son from a previous relationship.
In June 2021, Kaitlynn confirmed that she was expecting her first child.
In June 2021, Kaitlynn confirmed in an Instagram photo that she was pregnant with her first child, without sharing how far long she was at the time. The pic is a silhouette of her, featuring her baby bump, holding hands with boyfriend Kristopher, who's tagged in the photo. The caption is a simple black heart emoji.
Kaitlynn has reportedly been with Kristopher since May 2020. A source, per Entertainment Tonight, revealed that the couple wanted to keep the pregnancy news to themselves for some time before sharing it with the public: "They wanted to do something extra special just the two of them before they made the news public,” the source said.
Kaitlynn and Kristopher booked a babymoon at Esperanza, Auberge Resorts Collection, in Cabo, according to the outlet.
"She is obsessed with the spa at Esperanza and wanted to spend a couple days pampering herself," the source said.
She even posted some pics from the resort before announcing the pregnancy, but hid her belly in each one.
Kaitlynn said she and Kristopher have a "chill" relationship.
Kaitlynn has said that she wants to keep her relationship with Kristopher private, but it looks like things have changed. On a December 2020 episode of the Scrubbing In With Becca Tilley and Tanya Rad podcast (via E!), she said she's never been in a relationship like this before.
Kaitlynn also gave us a peek into her relationship on Instagram: "True story ... @kristopher.brock and I were introduced by a mutual friend over text last May," Kaitlynn wrote in May 2021. "I asked him out on a first date a few days later (unknowingly) ON HIS BIRTHDAY, May 18. He had plans with his son that night, but we got together for dinner on the rooftop of @thesurfridermalibu the following night ... and the rest is history ..."
Congratulation to Kaitlynn and Kristopher on their new bundle of joy!
