Kim and Khloé Kardashian reveal nickname for Timothée Chalamet amid Kylie Jenner romance

Call him by his name.

Kim and Khloé Kardashian revealed they call their sister Kylie Jenner’s boyfriend, Timothée Chalamet, “Timmy.”

The Kardashian sisters opened up about a recent family dinner hosted in Malibu, Calif., attended by Jenner and Chalamet.

“It was so nice. Just like 12 people. It was really small. We had so much fun,” Khloé, 41, detailed on her “Khloé In Wonder Land” podcast Wednesday.

“And I was like, but I wasn’t there like how mom [Kris Jenner] was there for like 10 minutes and left, which is fine. She was tired. We had a long day. But I was so proud of myself that, like, I stayed ’cause normally I’m like the first one to dip,” she added.

The “All’s Fair” star, 45, noted that she was “really proud” that Kylie, 28, came to the intimate dinner and “stayed ’til 1:30 in the morning.”

“I was so … Kylie had the best time … She stayed after me,” the Good American founder added.

“[Kylie] was the first one there,” Kim pointed out. “She was like the first one there and the last to leave. That was insane.”

Khloé added, “I was so proud of her. And her, Timmy, they had the best time.”

This is the first time the Kardashian sisters have spoken about Chalamet and Kylie’s romance, which first sparked in 2023.

Although reports surfaced last August that the “Dune” star and Jenner had split, they shut down the rumors by grabbing coffee together in Hungary.

Jenner and Chalamet, 30, initially made their red carpet debut in May 2025 at the David di Donatello Awards in Rome. They have since attended several high-profile events together, including the Critics’ Choice Awards 2026 and this year’s Golden Globes.

Page Six exclusively reported that the “Marty Supreme” actor and Jenner are living together in LA and act like they’re “basically married already.”

The Kylie Cosmetics founder shares daughter Stormi, 7, and son Aire, 3, with ex Travis Scott.
