Isaiah Hartenstein’s wife, Kourtney Kellar, says farewell to Knicks in heartfelt tribute

Kourtney Kellar is looking forward to her and Isaiah Hartenstein’s next chapter in Oklahoma City.

The model said goodbye to New York in a post on her Instagram after the soon-to-be former Knick agreed to a three-year, $87 million deal with the Thunder on Monday.

“Thank you for 2 amazing years New York! Going to miss this city & the great people in it 🫶🏼,” Kellar wrote, including a photo of her sporting Hartenstein’s No. 55 Knicks jersey while walking through the back hallways of Madison Square Garden.

Hartenstein added a red heart emoji in the comments.

Taking to her Instagram Stories, Kellar — who married the 7-foot-1 center last July — shared another photo of her standing on the court at The Garden cradling her baby bump.

The couple announced earlier this year they’re expecting a baby boy.

“Excited for the next chapter in OKC & so proud of you,” Kellar added in another post, which included a breaking news alert of Hartenstein’s new deal.

Hartenstein proposed to Kellar on the beach in Malibu in April 2022 with a stunning oval-cut diamond ring — and they tied the knot the next summer on a yacht in California.

The couple first met in 2019, when Hartenstein slid into Kellar’s DMs and complimented her smile, according to TMZ, which said the model was smitten over the gesture.

After a few FaceTime dates, they eventually met up in Houston, where he was playing for the Rockets at the time, and the rest is history.

Kellar, who is a former ring girl, relocated from Los Angeles to New York when Hartenstein joined the Knicks.

In 75 games played and 49 starts for the Knicks last season, Hartenstein averaged 7.8 points and 8.3 rebounds, while shooting 64.4 percent from the field.

The 26-year-old will add elite defense and rim protection to a young core in OKC that includes MVP candidate Shai Gilgeous-Alexander, Chet Holmgren, the No. 2 overall pick in the 2022 NBA Draft, and Jalen Williams, another first-round pick in that draft.

It came after the Bulls shipped Alex Caruso to Oklahoma City last month for Josh Giddey, the No. 6 pick in the 2021 NBA Draft.

The Thunder finished the regular season as the No. 1 seed in the Western Conference but were eliminated by the Mavericks in the second round of the playoffs.
