In one image, the 56-year-old actor leans in close to chat with Kardashian West as he grasps her hand with both of his hands. His Once Upon a Time in Hollywood co-star, Margaret Qualley, stands nearby smiling.
This isn't the first time Pitt has mingled with the power couple. Last year, he attended one of West's Sunday services and told ET that he thought the 42-year-old rapper was "doing something really special there."
“It's a pure celebration of life and people," he said of the service. "It's really delightful. It really is.”
At this Sunday's swanky affair, Kardashian West and her husband couldn't keep their hands off each other, even sharing some red carpet smooches.
On her Instagram Story, Kardashian West shared that the chain necklace West paired with his all-black outfit was the Christmas present she gave him. The mother of four also revealed to ET that West gifted her for Christmas with the stunning Alexander McQueen 2003 shipwrecked oyster gown she was wearing at the after-party.
"I would always stress out about big events like this and what would I wear and the last-minute part of it," she told ET. "So he kind of filled it up and got me a few really nice couture pieces so I wouldn't stress out."
The 39-year-old reality star also shared a video of herself lying down in the car on the way to the event, saying, "OK, I literally have to lay down in the car. Like, I cannot sit up because my dress will rip or pop or something -- but it's worth it."
On the carpet, Kardashian West also posed with her younger sister, Kylie Jenner, who had a similar issue with her sparkly navy gown.
"Couldn’t really sit in this but it was worth it ?," she wrote on Instagram, posting a pic of herself propped on her side in the car.
In addition to her younger sibling, Kardashian West posed with Caitlyn Jenner and Nicky Hilton inside the event.
