Jennifer Connelly Wraps Arm Around Husband Paul Bettany in Sunny Photo: 'Happy Valentine's Day to My Love'

Jennifer Connelly is giving her main squeeze a shoutout this Valentine's Day!

In honor of the loved-up holiday on Wednesday, the Oscar-winning actress posted a photo on Instagram of herself and Paul Bettany in a sunny locale, showing off their toned physiques in coordinating goldenrod-colored outfits: a bikini for Connelly, 53, and what appear to be shorts on her husband.

"Happy Valentine’s Day to my love @paulbettany ❤️," Connelly captioned her shot.

The WandaVision actor, 52, later reshared the post to his own Instagram Story.

Bettany and Connelly met while filming A Beautiful Mind in 2001, though they didn't begin dating until after the shoot. Since then, the pair have been inseparable.

A representative for Connelly confirmed to PEOPLE on Jan. 10, 2003, that the Labyrinth actress and Marvel actor quietly had wed over the 2002 holiday season.

They share son Stellan, born in 2003, and daughter Agnes, born in 2011, and also raised Connelly's son Kai (whom she welcomed in 1997 with photographer ex David Dugan) together.

Connelly and Bettany have worked together on several projects since A Beautiful Mind, including 2015's Shelter. They've also both appeared in Marvel Cinematic Universe films — Bettany was the voice behind Iron Man's J.A.R.V.I.S. and later starred as Vision, while Connelly played a small role in Spider-Man: Homecoming as Peter Parker's AI assistant Karen.

Connelly and Bettany's friendship blossomed into romance shortly after the shock of the 9/11 attacks — Bettany has said he realized he was in love with the actress after frantically worrying about her. He proposed to Connelly before they even dated and moved in with her in New York City.

"Yeah, totally faked my way into that one; poor Jennifer, as she slowly realized how ill-educated I was," he joked to PEOPLE in an exclusive chat back in 2021. "She's much better read than me. I just sound like it because of the English accent, that's all."

"Marriage and children changed my life," revealed the Knight's Tale actor. "It really altered who I was and what I saw as my goals."

Now the moments that mean the most to the actor are "when I catch myself and realize the five of us are laughing together," he said. "And there is nobody on Earth with whom I could be having a better time."
