You could say that Sophie Turner is a sucker for a man in pajamas.

After all, the Game of Thrones alum shared a photo of herself and husband Joe Jonas rocking matching sleep sets in celebration of his 34th birthday. In an image shared to Instagram Stories on Aug. 15, the couple—who are parents to daughter Willa, 3, and a 13-month-old child whose name has not been publicly revealed—posed in green striped PJs in the mirror of a walk-in closet.

Sophie, whose hair was braided into pigtails, snapped the selfie on her phone during their slumber party.

The 27-year-old wrote in the caption, "Happy birthday handsome."

The sweet tribute comes just days after Sophie was spotted in the crowd at New York City's Yankee Stadium to support Joe and the rest of the Jonas Brothers at their Five Albums. One Night. The World Tour. For the occasion, the actress donned an emerald sequin dress paired with an armful of friendship bracelets to trade with fans.

In a picture of her OOTD posted to Instagram Aug. 14, one of Sophie's bracelets read "Mr. Perfectly Fine," a nod to the Taylor Swift song about Joe. (The singers briefly dated in 2008, years before he started dating Sophie.)

Over the years, Joe has wooed Sophie with plenty of romantic gestures. As the musician previously explained to E! News, he once pretended to be out of town just so he could surprise her "when she least expected it."

"I think I did a good job of that," he said. "You play it off like you're somewhere else in the world. You're on FaceTime and hiding on a plane. I've gotten away with that before."
