NBA star Isaiah Hartenstein and Kourtney Kellar are married!

The couple said “I do” on July 29, 2023, in California. Their ceremony and reception took place on a yacht.

Hartenstein and Kellar first connected in 2019 when the New York Knicks player slid into the model’s DMs to compliment her smile. After messaging on the app for a bit, they met up in person for the first time and quickly began dating.

Three years later, the pair got engaged in April 2022, and they have since moved to Westchester, New York.

Kellar has also been a mainstay of Hartenstein’s career, supporting him at his games from the sidelines and making various NBA-related TikToks.

So, who is Isaiah Hartenstein’s wife? Keep reading for everything there is to know about Kourtney Kellar.

Kellar was born and raised in Dallas, Texas, as the youngest of three children, according to the New York Post. She attended Henderson State University in Arkansas for college, where she graduated in 2014 with a degree in athletic training. She first got into modeling as a way to pay for her education.

“I was a broke college kid and needed money, so I started modeling in Arkansas for brands like Dillard’s and Walmart,” she told the outlet during an October 2022 interview.

She is a model

In 2013 and 2014, she competed in the Miss Henderson State University Pageant, where she was first runner-up in 2013, according to the Sentinel-Record. After graduating college, Kellar wanted to model full-time. In 2014, she moved back to Dallas but had little success signing with an agency.

“After I moved back to Texas, I signed up for Miss Texas International and won that pageant [in 2017],” Kellar told the New York Post.

Following her tour as the reigning Miss Texas International, she began to model for Supercross as a Rockstar model and became a Tecate ring girl.

“My first fight was [Canelo Álvarez] versus [Gennady Golovkin II] in Las Vegas,” she said of the historic 2018 match. “All of these opportunities helped build my portfolio, network and social media presence.”

In 2021, she signed with the modeling agencies Lipps LA and Select Miami, which propelled her to walk in Miami Swim Week. She’s since walked at New York Fashion Week and been on the cover of Malvie magazine.

Hartenstein and Kellar first connected when the NBA player slid into her Instagram DMs.

“My Instagram is pretty sexy, so I get a lot of comments about my body, which is nice. But he came in and messaged me something like, ‘You have the most beautiful smile,’ and sent me his favorite photo of me from my feed,” she told the New York Post.

“I was wearing a turtleneck in that picture,” she added. “It was really sweet of him.”

Kellar was living in Dallas at the time, while Hartenstein was playing for the Houston Rockets, only a few hours away. She had FaceTime dates with Hartenstein for a few weeks before they met up in person.

“I confirmed he wasn’t a serial killer and we met up at a restaurant,” she joked. “It went so great and I was really excited.”

Prior to her relationship with Hartenstein, Kellar was in a relationship with country singer Chase Bryant. They began dating in 2015 and got engaged in September 2017. However, they eventually called off their engagement.
