Kourtney Kellar is savoring every moment of the Knicks’ playoff run.
In a video posted on TikTok last week, the model and ring girl — who is engaged to Knicks star Isaiah Hartenstein — can be seen modeling a pink Knicks bomber jacket from FISLL, a social impact apparel brand founded by former Knicks All-Star Allan Houston.
“A pink Knicks jacket? Yes, thank you,” Kellar wrote in her caption thanking the brand with the hashtag, “nbaplayoffs.”
The Knicks are currently tied with the Heat in their Eastern Conference semifinals series, 1-1.
Game 3 is set for Saturday in Miami.
Hartenstein, who signed a two-year deal with the Knicks last summer, has recorded five points, 11 rebounds and two assists through the series thus far.
New York took Game 2 on Tuesday with a 111-105 win in front of a star-studded Madison Square Garden crowd while Miami opened the series Sunday with a 108-101 victory.
Kellar joked about Hartenstein’s apparent celebrity doppelganger, rapper Jack Harlow, in a separate TikTok video following the performer’s appearance at Game 1.
“People saying @Jack Harlow and @Isaiah Hartenstein look alike,” the model wrote, adding a crying-laughing emoji.
In another TikTok video posted last week, Kellar — a Texas native who won the 2017 Miss Texas International title — gushed over the couple’s future nuptials while dancing in Hartenstein’s No. 55 jersey.
“Mood: proudly wearing my fiancé’s 3xl jersey on game day with the last name I’m about to have in 3 months,” Kellar wrote over the video, revealing the pair will tie the knot this summer.
“@zayhart55 I’ll be bringing these dance moves to the wedding,” she added in her caption.
Hartenstein popped the question to Kellar at the beach in Malibu last April, one week after his season with the Clippers ended.
The NBA star proposed to Kellar with a stunning oval-shaped diamond ring.
“Excited for the next part of our journey!! Love you,” Hartenstein gushed on Instagram at the time.
The couple began dating in February 2019 after Kellar ended her engagement to country singer Chase Bryant.
Kellar, who has more than 452,000 followers on TikTok, frequently features Harternstein in her videos, including one clip when she attempted to train the NBA big man in how to take Polaroid pictures.
Although the influencer is based in New York now, she is still signed to Lipps LA modeling agency, as well as Select Model Management in Miami.
Kellar also served as the ring girl at the Jake Paul-Anderson Silva fight in Arizona last October.
The blonde beauty has worked with several high-profile brands and publications, including Maxim magazine, Guess, and Fashion Nova.
Kellar began modeling at the age of 14 when she was approached by Varsity, a brand of cheerleading uniforms.
She has modeled activewear, swimsuits, and lingerie, and is a runway staple at Miami Swim Week.
Though Kellar has been actively supporting Hartenstein this postseason, she is also mourning the tragic loss of her mother, Michelle Kellar.
The model said in April she returned home to help with the funeral arrangements.
