Kendall Jenner and Boyfriend Blake Griffin Walk the Red Carpet — Separately

Kendall Jenner and boyfriend Blake Griffin nearly made their red carpet debut on Wednesday night.

The couple both attended the premiere of The 5th Quarter in Beverly Hills, California, each posing for photographers separately.

Jenner, 22, showed off some skin a mesh leotard — which she paired with ripped jeans, a beige blazer and peach-colored bra. The Keeping Up with the Kardashians star accessorized her look with black boots and a gold cross necklace, while wearing her hair back in a loose bun to show off her smiling face and natural-looking makeup.

Though Griffin wasn’t by her side, she did throw her arm around CEO of OBB Pictures Michael Ratner, who kept things cool in black jeans, a grey hoodie and maroon bomber jacket.

Griffin, meanwhile, dressed down his fitted royal blue suit with a grey crewneck sweater and white sneakers.

Jenner and Griffin, 28, have been hanging out since August — shortly after he split from the mother of his two children, Brynn Cameron, a former college basketball player.

Other hangouts include getting into costume at a Halloween party and grabbing a bite at Sugarfish Sushi in Beverly Hills on Sunday. He was also with Jenner and her family at her birthday dinner at Petit Taqueria earlier this month.

“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.”

Another source added: “Kendall is very happy with Blake. They started out more like friends, and then it was very casual. But it seems more serious lately. 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.”
