This isn't the first time Kendall Jenner and Ben Simmons' mom Julie have been photographed spending time together at one of the NBA star's games

Kendall Jenner is showing Ben Simmons her full support — and bonding with his family in the meantime.

The 23-year-old reality star and supermodel was snapped sitting courtside with Simmons’ mom Julie during a 76ers game in Philadelphia on Monday night, when the athlete’s team took on the Houston Rockets.

For the evening, Jenner wore an oversized green sweatshirt and had her dark hair tied up in a bun, finishing the look with a pair of gold hoop earrings and ring featuring a bright-blue center stone.

In one photograph, the duo looked fully engrossed in the action in front of them. The 76ers bested the Houston Rockets by almost 30 points, with a final score of 121 to 93.

This isn’t the first time Jenner and Simmons’ mother have been photographed spending time together at one of the basketball star’s games. On Nov. 30, the pair sat side by side in Philadelphia as the 76ers squared off against the Washington Wizards.

Seeming to get along with the proud mom, the Keeping Up with the Kardashians star was photographed laughing and smiling as the pair interacted.

And the duo’s presence seemed to be good luck then, too. The 76ers walked away with another large-margin win, earning 123 points to the Wizards’ 98.

Jenner was first romantically linked to the Australian basketball star, 22, over the summer, but they appeared to cool things off going into the fall before Jenner was photographed at his games starting in November.

While her outings with Simmons’ mom — and public displays of affection on social media — hint that the pair may be getting serious, they have yet to define their relationship publicly.

“Kendall was spending time with Anwar [Hadid], but that ended and she started hanging out with Ben again. She hasn’t seen Anwar recently,” a source told PEOPLE just last month about the model’s link to Gigi and Bella Hadid‘s 19-year-old younger brother.

“When she’s not working, she’s been focusing her free time on Ben and flying to Philadelphia,” the insider added of Jenner. “They’re still not exclusive though.”
