Joe Jonas is celebrating his soon-to-be wife!

The 29-year-old DNCE singer took to Instagram on Thursday to reveal that he threw fiance Sophie Turner a surprise birthday party on Valentine’s Day, just before her 23rd birthday on Feb. 21.

Some of the sweet photos from the party show the Game of Thrones star, clad in a black dress, hugging and kissing Jonas, who’s wearing a geometric patterned T-shirt and dark pants, as they stand in front of a large heart made up of balloons. 

Other pics include Turner’s surprised face as she walks into her bash, the birthday girl posing with girls dressed in red balloons and feather headpieces, and a group photo of many of the attendees doing shots

“My Valentine gets a surprise birthday party because she’s the f**king best. 😍,” Jonas wrote alongside the pics.

Turner got in on the Valentine’s Day love too, sharing a sweet snap of her and Jonas smiling lovingly in front of a tree. In the pic, Jonas is grinning for the camera, while Turner keeps her eyes and smile focused right on her fiance.

“Happy Valentine’s Day my love,” she wrote. “You make me the happiest.”
