Kendall Jenner and Blake Griffin were not all that fazed when the Los Angeles Clippers lost against the New York Knicks.

On Monday, Griffin's team lost to the Knicks, 87 to 105. After the game, Griffin and the "Keeping Up with the Kardashians" star partied for the rest of the night. They were spotted leaving Up & Down nightclub in Manhattan around 3 a.m. on Tuesday morning, TMZ reported.

According to the publication, Jenner was at Madison Square Garden to watch her boyfriend's game. Despite her presence and Griffin's efforts, the Clippers did not win, making this the team's ninth loss in a row.

Since Jenner and Griffin's relationship was confirmed, the E! personality has been spotted out and about with the NBA superstar multiple times. Earlier this month, the supermodel also cheered on Griffin during Clippers' game against the Memphis Grizzlies. However, Clippers lost the game 113 to 140.

Meanwhile, rumors have claimed that some of the athletes who have been romantically involved with the Kardashian-Jenner ladies suffered plummeting careers. Sources dubbed this as the Kardashian Curse. Among the affected players is Khloe Kardashian's ex Lamar Odom, who is no longer playing for the NBA. Cristiano Ronaldo was also once involved with Kim Kardashian and during that year, he was not named as one of the world's two best players. This was the only year that the Real Madrid footballer had failed to collect a trophy.

Houston Rockets' James Harden also previously dated Khloe. But the shooting guard ended their romance immediately as he did not like the attention he received from dating a reality star. "[Dating a Kardashian] wasn't me," Harden said.

At the moment, Khloe is dating Tristan Thompson, and unlike her previous romances, their relationship has been smooth sailing. In fact, the couple is rumored to be expecting their first child together. But while Khloe and Thompson's romance continued to heat up, the Cleveland Cavaliers lost the NBA championship to the Golden State Warriors last season.

As for Kendall and Griffin, the couple's relationship is going strong. In fact, when she celebrated her 22nd birthday, the Clippers player was among her guests.

"They're legit. They're a full-on couple," one insider 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. They're good."
