Justin Bieber shares adorable throwback with Hailey Baldwin ahead of their wedding

Justin Bieber shared an adorable throwback photo with Hailey Baldwin ahead of their second wedding.

The couple secretly wed in a New York courthouse in September 2018, just a few months after they got engaged. And as they are set to say 'I do' again on Monday, the Canadian singer shared a throwback photo from "where it all began". "My wife and I," he captioned the photo of the two of them as teenagers, along a smiley face emoji. "Where it all began." The couple are expected to get married for the second time on Monday, September 30. A Bieber source told PEOPLE that the couple "always planned" to have a religious ceremony, after their civil ceremony last September. The insider continued:

“Justin and Hailey are having a wedding ceremony and party in September. Since they only had a civil ceremony, it’s very important to them to have religious ceremony as well. “They always planned to have one. They want to wed properly in front of family and friends.”

They added that the wedding party will be held at Montage Palmetto Bluff, after the singer had previously spent some time at their location in Laguna Beach. The source said:

“The Montage has long been like a second home to Justin. “He many times escaped to the Montage when he needed some quiet time. They both love the Palmetto Bluff Montage. “Hailey’s wedding planner is working with local vendors to create the most special ceremony and celebration."
