Oklahoma City Thunder center Isaiah Hartenstein was a guest at the ESPYs this week and as always his wife Kourtney was at his side and turning plenty of heads.

For the awards show this week Kourtney Kellar showed off a gorgeous brown dress with a low cut to the chest. Meanwhile, Isaiah wore an olive-green suit and paints over a white button down shirt with no tie.

“The ESPYS 2025 ✨Stylist @dan.solomon_, Assisted by @sofiahristidis, Makeup @leyla__hayauri, Hair @hairbyruslan, #espys #espyawards,” she wrote.

Kellar’s many fans loved the post, with many remarking that the two were the best-looking couple at the entire event.

“Best dressed couple at the ESPYS?!” one user wrote on Instagram.

“You look stunning!!!” wrote another.

“Power couple,” a third declared.

“You look great guys!”

“You look so good!”

Unusual way Knicks' Isaiah Hartenstein hit on Kourtney Kellar

 

Kourtney Kellar has been a model and influencer for years and has built a large following on social media with over 650,000 followers on Instagram alone. Arguably her biggest claim to fame was her work as a ring girl for boxing matches.

Outside of her work as a ring girl, Kellar has been a model for years. Her work has gained her tons of fans who appreciate all of the different career hats she wears:

“I love Kourtney! So simple when not in the ring, doesn’t brag how gorgeous she is,” one user wrote on her Instagram.

“You are gorgeous! Now I want to watch this fight just to see you on the ring!!” wrote another.

“Bright, smart, and beautiful!” a third declared.

Kellar and Hartenstein admittedly met through Instagram several years ago and ultimately got engaged in 2022. The two were married in 2023 and welcomed their first child – in 2024.

Hartenstein has bounced around the NBA for a few years now. He played for four different teams between 2018 and 2022 before signing with the New York Knicks. After his time in New York ended, he signed a three-year, $87 million contract with the Thunder.

The 2024-25 season ended with Hartenstein and the Thunder winning their first NBA title since moving to Oklahoma City.

Not a bad couple of months.
