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 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."
