Ryan Gosling gives subtle shoutout to Eva Mendes on press tour with T-shirt

This Ken is wearing his heart on his sleeve.

Ryan Gosling showed his support for Eva Mendes’ career during an interview with the UK’s Hits Radio on Monday, choosing to wear a shirt that promoted his partner’s upcoming project as he chatted about his own new movie.

The “Barbie” actor, 43, sported an ivory tee reading “Desi, Mami and the Never-Ending Worries” — the title of the Skura Sponge owner’s debut children’s book ($20) — as he sat next to his “The Fall Guy” co-star, Emily Blunt, to chat about their action comedy.

The illustrated book, which releases September 17, tells “the story of a little girl facing endless scary worries” at bedtime and how her mother helps her overcome them.

While Mendes, 50, has been taking a break from acting, she’s now adding “author” to her résumé, telling People, “Desi, Mami and the Never-Ending Worries is a love letter to my kids and yours.”

This isn’t the first time the “Notebook” actor has worn a tribute to his longtime love while promoting one of his films; he wore an “E” necklace at the “Barbie” premiere in Los Angeles last summer.

And the “Hitch” star is just as supportive of Gosling’s career, showing off a Ken T-shirt with her partner’s photo on it while the actor promoted “Barbie” last summer.

While the notoriously private couple has never officially confirmed that they’re married, Mendes did call the “La La Land” star her “husband” during a November 2022 interview.

She also showed off a tattoo tribute to Gosling in 2022 that reads “de gosling,” hinting that she might have added Gosling’s last name to hers by adding “de,” meaning “of” in Spanish.
