The "Sorry" singer, 25, and his model spouse, 22, walked down the aisle in a more formal big white wedding ceremony on the coast of South Carolina on Monday, September 30.
The couple said "I Do" at Somerset Chapel right at sun set at the Montage Palmetto Bluff in Bluffton.
Just before the wedding, guests reportedly enjoyed pre-ceremony cocktails at the Inn lobby lounge.
Following the vows, guests were escorted to the post-ceremony cocktail hour ahead of the formal reception with plated dinner at the Wilson
Party planner to the stars Mindy Weiss reportedly arranged the wedding details.
R&B singer Daniel Caesar is expected perform at the reception.
As RadarOnline.com previously reported exclusively, the 154 guests — including models Kendall Jenner, Camila Morrone and Joan Smalls, as well as Bieber’s manager Scooter Braun — were all warned that giant gators would be roaming nearby the 20,000-acre resort.
Alligators in the area are known for climbing up onto the river bank within meters of rental cottages.
But sources said they always planned to throw a later “big blowout” wedding with friends and family.
It took time, with the couple reportedly attempting to schedule the second ceremony four times before it actually happened.
Although the Canadian-born pop star and Baldwin have no connections to South Carolina, they apparently loved the Palmetto state for their wedding location.
Bieber and his bride have had a slew of relationship issues. Days after saying “I do,” he was pictured crying uncontrollably while driving around with Baldwin.

Baldwin “exploded” after finding text messages from Justin's ex-girlfriend Selena on her husband's cell phone, a source said.
Bieber has admitted suffering from mental health issues, while Gomez fully recovered from her own mental breakdown last October.
The insider told RadarOnline.com at the time, “There is truly nothing that Hailey can do to change how Justin feels. He is talking to Selena again and the two of them are on good terms.”
Baldwin has admitted to Vogue, "Marriage is very hard," while Bieber said, "We don’t want to lose each other. We don’t want to say the wrong thing, and so we’ve been struggling with not expressing our emotions, which has been driving me absolutely crazy because I just need to express myself, and it’s been really difficult to get her to say what she feels.”
The beautiful model and daughter of actor Stephen Baldwin added, "I love him very much.”
The two have admitted to attending couple’s therapy.
