The Instagram photo shows a shaggy-haired Bieber flashing a big smile while standing closely to Baldwin, who is flashing a peace sign.
“My wife and I 🙂 where it all began,” Bieber captioned the photo.
The singer and model have been friends since they were teenagers, but that changed in 2016 when a romance began. The pair was legally wed last year in a Manhattan courthouse.
Bieber’s throwback pic drew reactions from some of his famous IG followers, including Justin Timberlake, who commented, “That’s incredible, bro!!!” Kylie Jenner added, “This is amazing.”
Bieber and Baldwin are reportedly set to have a traditional second wedding ceremony in South Carolina this weekend with friends and family.
