The secret behind Goldie Hawn's 33-year relationship with Kurt Russell? Never marrying.
"I would have been long divorced if I'd been married," Hawn told the hosts of the British talk show "Loose Women."
"Marriage is an interesting psychological thing," said the legendary "First Wives Club" star. "If you need to feel bound to someone, then it's important to be married."
"If you have enough money, and enough sense of independence and you like your independence, there's something psychological about not being married," she continued. "It gives you the freedom to make decisions one way or the other."
The twice-divorced Hawn, who stars opposite comedian Amy Schumer in an untitled mother-daughter comedy set to hit theaters next year, said her long union with Russell works because both know they choose to be together.
"For me, I chose to stay, Kurt chose to stay, and we like the choice," said the 70-year-old Oscar winner.
Together, the couple raised three children —their son, actor Wyatt Russell, 30, and actors Oliver Hudson, 40, and Kate Hudson, 37 — Hawn's kids with her ex-husband Bill Hudson.
The "Private Benjamin" star revealed that she and 65-year-old Russell asked their kids about 10 years into their union if they'd prefer mom and dad got hitched.
"And they went, 'No!' " Hawn said, emphatically. "They loved it. It was perfect the way it was."
Though she and Russell hit the jackpot in love, Hawn said not all relationships are meant to last forever.
"Not every relationship works and that is the truth," said Hawn. "I don't care if you're a movie star or a person on the street."
