Justin and Hailey Bieber Wed Again One Year After Legally Tying the Knot

Justin and Hailey Bieber have said 'I do' for the second time.

Justin and Hailey Bieber have said "I do" for the second time, ET can confirm.

After legally tying the knot last September at a private courthouse ceremony in New York City, the couple wed again -- this time with a more formal wedding party and surrounded by their family and friends -- at the Montage Palmetto Bluff in Bluffton, South Carolina. ET has learned that event planner to the stars Mindy Weiss helped Justin and Hailey plan their wedding weekend.

Justin and Hailey tied the knot on Monday evening, according to the outlet. A reported 154 guests were in attendance for the ceremony at Somerset Chapel, including Kendall Jenner, Scooter Braun, Camila Morrone and Joan Smalls. A second source tells ET that Ireland and Alaia Baldwin were bridesmaids in the ceremony.

"Residents from around the neighborhood [that live] close to wedding were cheering loudly when they made it official," a third source notes.

Before the wedding guests were treated to cocktails at the Inn lobby lounge, and afterwards, they enjoyed another cocktail hour ahead of a formal reception. According to People, Daniel Caesar is expected to perform later in the evening. 

The night before their nuptials, the couple, according to the third source, even screened The Notebook for their guests. The movie came after their rehearsal dinner, which took place in Cole’s lounge in the building in front of the movie screen. The screening, the source says, took place in the Moreland Village area of the resort’s property. 

"There were beanbags and pillows set up on the ground in front of a large movie screen with a stage near it," the source shares.

Prior to the wedding, a source told ET that Hailey was taking time to pamper herself, and she also had a fun bachelorette party with her close pals, including Jenner, on Sept. 25 in West Hollywood, California. Hailey glowed in a fitted white dress and sported a veil for the occasion.

Meanwhile, a source also told ET that Justin was in "a good place" ahead of the wedding.

"Justin has been through a lot in the past with his family, and he is looking forward to celebrating the special day with everyone," the source said. "Justin has had his ups and downs but Hailey is his constant rock through tough times like this. Justin is going into his upcoming wedding weekend in a very good place, looking forward to showing everyone the love he and Hailey share."

A source confirmed to ET last October that 25-year-old Justin and 22-year-old Hailey got married just a few months after he proposed last July.

"The couple kept their marriage a secret from a lot of people," the source said. "Justin and Hailey wanted to be married and didn't want to wait. They still plan to have a more formal wedding, but for them, this intimate ceremony was exactly what they wanted."

In June, the two debuted their wedding bands.

Since getting married, Justin and Hailey haven't been shy about showing PDA and professing their love for one another on social media. Last month, the singer said his wife was "the greatest thing that has ever happened" to him.

"I fall more in love with you every single day," he wrote alongside pics of the model. "You are the greatest thing that has ever happened to me. I would be lost without you. #wifeyappreciationday."

In July, Hailey said she had "baby fever" when commenting on Kylie Jenner's Instagram post of her boyfriend, Travis Scott, with their 1-year-old daughter, Stormi. Justin also made it clear he wanted children with Hailey in an Instagram post that same month.

"Love dates with you baby," Justin captioned a shot of the two at Disneyland. "One day I'll be doing daddy daughter dates….. not hinting at anything soon I'm not in a rush. I just wanna enjoy you by yourself for a while!"

The couple opened up about their marriage in a candid interview with Vogue for their February issue.

"The thing is, marriage is very hard," Hailey admitted. "That is the sentence you should lead with. It's really effing hard."

"It's just that I'm fighting to do this the right way, to build a healthy relationship," she added. "I want people to know that. We're coming from a really genuine place. But we're two young people who are learning as we go. I'm not going to sit here and lie and say it's all a magical fantasy. It's always going to be hard. It's a choice. You don't feel it every single day. You don't wake up every day saying, 'I'm absolutely so in love and you are perfect.' That's not what being married is. But there's something beautiful about it anyway -- about wanting to fight for something, committing to building with someone."

As for Justin, he told the magazine that he was more in-tune with his feelings than Hailey, who considers herself to be a more logical thinker.

"I'm the emotionally unstable one. I struggle with finding peace,” Justin acknowledged. "I just feel like I care so much and I want things to be so good and I want people to like me. Hailey's very logical and structured, which I need. I've always wanted security -- with my dad being gone sometimes when I was a kid, with being on the road. With the lifestyle I live, everything is so uncertain. I need one thing that's certain. And that is my baby boo."
