Kurt Russell is no stranger no rocking some pretty impressive facial hair for a movie role, but when it came time to star in Quentin Tarantino's epic Western The Hateful Eight, the 64-year-old star kicked his mustache up a few notches.

ET caught up with the now clean-shaven Russell and his longtime love, Goldie Hawn, at the Los Angeles premiere of his new action epic, and the happy couple opened up about the effect his massive mustache had on their relationship.

According to Hawn, Russell's facial hair wasn't just a fashion choice, it "was a lifestyle."

"It was like, 'Where are those lips?" I didn't see them for a year and a half," the actress quipped.

While the two seemed relieved to not have that facial hair between them, it seems like Russell could have used the extra warmth, considering their holiday plans.

Hawn revealed that the family was going to spend some quality time during the winter at their place in Aspen, Colorado.

"That's our homestead," Hawn shared. "That's where Santa comes."

"We have five grandkids now, so they love it there," Russell added.

In The Hateful Eight, Russell plays tough-as-nails bounty hunter, John "The Hangman" Ruth, and he spends most of the film shackled to his captive, a deadly fugitive named Daisy Domergue, played by Jennifer Jason Leigh.

According to Hawn, she warned Russell that he was going to fall for his lovely co-star after spending so much time chained together.

"I told him! I said he's gonna fall in love," Hawn joked. "It's the Stockholm syndrome, you know?"

"You don't want to fall in love with what I'm chained to," Russell said, referring to the murderous criminal Leigh plays inThe Hateful Eight. "That's a bad mistake."
