Dolph Lundgren, 67, reveals the ’simple secret’ behind marriage to wife Emma, 29

Dolph Lundgren has shared what he dubs his 'secret' to a strong marriage.

The Swedish actor is best known for starring in movies like Rocky IV, Creed II, and The Expendables, and officially became an American citizen alongside his wife, Emma Krokdal, last year.

Krokdal, who is 38 years Lundgren's junior, wed the Hollywood star in 2023. Their marriage marks Lundgren's second, having previously been married to Anette Qviberg for almost 20 years.

While his marriage to Krokdal is relatively new, the actor says he has a 'secret' to keeping it strong.

"I have this new thing, I have to give her a hug, a nice big hug, 10 times a day," he revealed to Fox News.

"I try to get a few before lunch," Lundgren continued to gush. "So I still have some in the bank [throughout the day]. It sounds simple and a little goofy, but doing that neutralizes a lot of disagreements and misunderstandings. And it makes us both feel good. That’s my new recipe now."

The Rocky favorite went on: "When you have disagreements, somebody wants to be right, but the other person also wants to be right. But you have to make your partner feel good, even when you both have disagreements.

"That phrase [‘happy wife, happy life’] is true. You have to respect each other. You have to compliment each other."

Elsewhere, Robert Downey Jr. and his wife of 22 years swear by a 'two-week rule'.

The Iron Man star has been married to Susan Downey since 2003 and shares two kids with her: Exton, born in 2012, and daughter Avri, born in 2014.

Downey also has a 31-year-old son, Indio, with ex Deborah Falconer.

Sharing the rule that's kept their marriage going for so long, Susan previously shared with PEOPLE: "We do have a two-week rule, which often feels too long, but we don't go more than two weeks without seeing each other and the family being together."

"Fortunately, we prefer to be a traveling circus when we can be," she went on.

Susan went on to credit her job as a producer for allowing her to be more flexible in comparison to her husband's job in front of the camera.

"The good news is I'm not in front of the camera, and so as a producer I end up with a little bit more flexibility in terms of location, of where I would need to be," she said of this.
