During the couple's recent lakeside getaway, the Phoenix Suns player snapped a picture of the model proudly donning the gold medal he won as a member of the U.S. men's basketball team at the 2020 Tokyo Olympics.
This was one of many vacation photos Devin shared with his 4.4 million Instagram followers. He also posted one of himself swimming in the water and a few images of his dog enjoying a boat ride, captioning the Aug. 17 series "LAKE BOi."
This isn't the first time Kendall has celebrated her boyfriend's major victory. After the U.S. team won its final game against France in Tokyo, the Keeping Up With the Kardashians star took to Instagram to show her support by placing a gold medal emoji over a picture of Devin in his jersey.
Of course, Kendall's gesture should come as no surprise to her fans.
Devin has also shown his support for Kendall, such as by sending her a gorgeous cactus display in the shape of "818" when she launched her tequila brand.
However, the couple, who have been dating for more than a year, still try to shield their relationship from the limelight.
"I think it makes my life a lot easier," Kendall said during the Keeping Up With the Kardashians reunion, "and our relationship a lot better, to be honest...I just feel like it's a private matter and not for anybody else to judge or know."
