The couple is currently preparing for their upcoming ceremony, which is set to be this upcoming Monday.
On Friday, the singer, 24, shared a sweet throwback photo of him and the model, 21, from back in the day. In the shot, above, a shaggy-haired "Baby"-era Bieber is seen smiling next to a teenage Baldwin as she throws up a peace sign.
"My wife and I :) where it all began," Bieber captioned the photo.
The adorable pic didn't go unnoticed by the couple's friends and family.
Kylie Jenner commented on the post, "This is amazing!" Bieber's mom, Pattie Mallette, wrote, "Oh my heart How adorable!"
Canadian singer Daniel Caesar, who is performing at Bieber and Baldwin's wedding, expressed he loved the shot with a heart emoji.
Bieber and Baldwin, who have known each other since they were teens, celebrated their one year wedding anniversary earlier this month. Last September, the pair tied the knot at a New York City courthouse.
The couple is currently preparing for their upcoming second wedding, which is set to be this upcoming Monday, according to TMZ.
The lavish wedding will include a religious ceremony and will be taking place at the Montage Palmetto Bluff in South Carolina.
"They are both beyond excited to celebrate with friends this weekend," a source close to the couple told People. "They are happy that they are finally having a religious ceremony. It's very special for them."
"This past year has really been a test for them. A test on their marriage. They are very proud of how far they have come," the insider added. "Justin is doing much better. He keeps focusing on his music and seems excited about it."
