Kendall Jenner Borrows Boyfriend Blake Griffin's Jacket After Attending His Stand-Up Comedy Show

Kendall Jenner cozied up in boyfriend Blake Griffin’s jacket after supporting the Los Angeles Clippers power forward’s stand-up comedy show for his Team Griffin Foundation in Hollywood Thursday night.

The 22-year-old model joined a crew of Griffin’s NBA friends for her boyfriend’s performance and went for a business casual look in a lightweight Tom Ford long sleeve turtleneck, Tom Ford check wide-leg trousers and slouchy Tom Ford over-the-knee boots.

Jenner seemed to get a little chilly by the time she slipped out of the venue with Griffin close behind and threw her boyfriend’s Ermenegildo Zegna coat (which has his name inscribed on the inside) over her shoulders.

After posing for a few photos right before the show was set to start, Jenner took her seat with a group of basketball players to see Griffin take the stage. According to an onlooker at the event, “Kendall was enthusiastic throughout Griffin’s opening performance, but in the middle of a set by John Mulaney, she and several of the other basketball players went backstage.”

Jenner and Griffin have been seeing each other since August, shortly after he split from the mother of his two children, Brynn Cameron, a former college basketball player. The couple’s been spotted together often since, with Jenner frequently sitting court side to watch Griffin play at L.A. Clippers games.

“Kendall is very happy with Blake. They started out more like friends, and then it was very casual. But it seems more serious lately,” a source previously said. “When they are not together, they keep in touch over the phone. Her family has accepted Blake. They are spending time getting to know him.”

Jenner and Griffin nearly made their red carpet debut together last week, when the duo both walked the carpet at the premiere of The 5th Quarter — separately.

“Kendall was in a great mood,” an onlooker told PEOPLE of the supermodel at the event. “She and Blake hung out, but they also mingled separately.”
