After the U.S men's basketball team won the gold medal in Tokyo, the model posted a picture to Instagram to celebrate Devin Booker, her boyfriend.
Jenner, 25, posted a picture of her TV and a photo of the Phoenix Suns player of 24 years. Jenner captioned the snap by adding an emoji for a gold medal.
With an 87-82 win over France, the team won the finals and earned the Americans their fourth consecutive gold medal.
After denying rumors for months, the couple finally went Instagram-official on Valentine's Day 2021.
The couple celebrated their one-year anniversary in June, posting snaps to mark the occasion. Jenner shared a photo of them together, while Booker posted a sunset shot with the words "1" and Kendall's name.
Jenner, who was previously linked to NBA players Ben Simmons and Blake Griffin, has always been extremely private about her love life compared to her reality show siblings.
"Kendall's always had this rule -- she just felt like she had to be with someone for at least a year before she lets them be a part of the show, because she doesn't always know what people's intentions are," an executive producer of "KUWTK" revealed recently as the hit series came to an end.
