Kendall Jenner attended the Philadelphia 76ers basketball game on Friday, apparently cheering on her reported boyfriend, Ben Simmons.

The team lost to the Cleveland Cavaliers, clocking the Sixers' first defeat at home this season.

In response, Sixers fans started a petition to ban Jenner from home games at the Wells Fargo Center. It currently has nearly 10,000 signatures.

"It [the loss] was inexplicable and Jenner's detrimental behavior is clearly to blame," the petition reads.

Other fans have come to her defense.

Kendall Jenner was spotted cheering on her reported boyfriend, NBA star Ben Simmons, at the Philadelphia 76ers basketball game on Friday — behavior that Sixers fans have dubbed "detrimental" to the team.

After the Sixers lost to the Cleveland Cavaliers, clocking the team's first defeat at home this season, Philadelphians responded by launching a petition to ban Jenner from the Wells Fargo Center.

"It is not a coincidence that the Sixers, who had started the season 10-0 at home, lost their first home game of the year the first time Jenner shows up," the petition reads. "It was inexplicable and Jenner's detrimental behavior is clearly to blame."

"At this point, Jenner is not only damaging the future of this franchise but the livelihood of innocent men as well," it continues. "It is disgusting behavior on her part."

"If the Jenner/Kardashian family has any shred of decency left, Kendall will never again show her face at the Wells Fargo Center."

The petition, which was started by Philadelphia native Aidan Powers, calls the Kardashian-Jenners a "notorious, career killing" family.

A Twitter user by the same name has tweeted about the petition numerous times, imploring fellow Sixers fans to sign and help "rid ourselves of this Kardashian evil."

Other Sixers fans, however, have come to Jenner's defense. Some have noted — as Katie McInerney wrote for the Philadelphia Inquirer — that blaming Jenner for a poor performance by professional basketball players has sexist implications.

A smaller (and notably less popular) petition to keep Jenner around was started in response to the original.

"According to TMZ Sports, Ben and Kendall got back together on November 3rd. Since then, the Sixers are 9-4 and are now 1.5 games out of 2nd place in the East. The numbers simply aren't bearing out a Kardashian curse," the second petition reads.

According to E! News, Simmons and Jenner are dating again but "aren't boyfriend and girlfriend."
