It was date night for Kurt Russell and Goldie Hawn!

The longtime couple hit up the Hollywood premiere of Marvel’s Guardians of the Galaxy Vol. 2, in which Russell plays Chris Pratt’s father, on Wednesday night, adorably posing together and looking as stylish as ever.

“I’m always proud of him, and I’m proud of him with this [film], but I haven’t seen the movie yet!” Hawn, 71, adorably gushed to ET’s Cameron Mathison on the purple carpet at the Dolby Theatre.

“She’s honest,” Russell, 66, agreed. “He’s never bad,” Hawn chimed in.

Hawn and Russell, who have been together for more than three decades, revealed that their grandchildren were also in attendance -- easily making them the coolest grandparents.

“Our littlest grandson, he decided he wanted to wear a tuxedo tonight,” shared Hawn, who is about to make her big-screen return for the first time in 15 years with Amy Schumer’s Snatched.

“I think our stock is going up right now!” Russell added with a laugh.

Wednesday also marked Hawn’s daughter Kate Hudson’s 38th birthday, and Hawn revealed she was spending her big day “having a nice dinner with her friends.”

As for their birthday gifts to Hudson? An orange tree from Hawn (“I like to get something that will last,” she said) and flowers from Russell.

One of the couple’s films, 1987’s Overboard, is being remade with Anna Faris taking on Russell’s role and Mexican actor Eugenio Derbez playing Hawn’s part. When asked if they would be open to making cameos in the upcoming film, Hawn and Russell were coy.

“No interest at all,” Russell said, half-jokingly. “I mean, they got to make their way man! They got to do whatever they do.”

“Watch television! It runs every week! It’s on a loop, so they don’t need us to pop in,” Hawn added.

But eventually, Russell seemed to warm to the idea of an appearance. “I can be bought cheaply, so throw a number out there,” he said with a laugh.

Just don’t expect Hawn to be joining him: “Not me, honey!”
