According to a new report, the 22-year-old Keeping Up With the Kardashians star and model attended the basketball game at the Staples Center in Los Angeles on Monday night. She was seen sitting courtside with her friends.
On Nov. 14, the Daily Mail posted images of the model cheering Griffin on just one day after they had a romantic dinner date at Sugarfish restaurant in Beverly Hills. In the photos, Jenner was seen wearing a gray outfit with a T-shirt and jeans, which she paired with textured snake-print ankle boots.
During the game, Jenner was seated beside Griffin's longtime friend, producer-director pal Michael Ratner, and boxer Flloyd Mayweather.
Jenner and Griffin were first spotted together in August, just weeks after Griffin ended his relationship with former fiancée Brynn Cameron, the mother of his two children.
"They're a full-on couple," a source told Us Weekly. "Kendall has been going to a lot of his games and they have been enjoying time at home when Blake is in town."
Before striking up a romance with the basketball player, Jenner was linked to rapper A$AP Rocky for over a year. She was also linked to Jordan Clarkson in 2016 but never confirmed she was dating either one of the men.
Although Jenner and Griffin have remained quiet about their relationship since starting to date in August, a source told Hollywood Life last month that the couple was already talking about starting a family someday.
“She is nowhere near ready to start a family with her new boyfriend Blake but the pair are heating up and have joked about what an amazing athlete their son would be, if they had a boy," the insider explained.
"Kendall was joking with Blake about their incredible genetics that would produce a super athletic baby capable of going to the Olympics, playing in the NFL or definitely in the NBA," the insider added.
Jenner and Griffin haven't yet publicly confirmed their reported romance.
