After landing in South Carolina on Saturday night, Bieber and Baldwin spent Sunday with family members, including his mom and her parents.
The couple held a rehearsal dinner which a source said seemed to be for close family members. At the event, Baldwin, 22, wore a white short off-the-shoulder dress accessorized with a white ribbon in her hair and white ribbon heels while Bieber, 25, kept it classy in a white polo tucked into black slacks paired with boat shoes.
For the rehearsal dinner, the source says the guests arrived at the Moreland Landing venue via speed boats.
“Justin and Hailey took a speedboat down the river to the rehearsal dinner. They both seemed beyond excited. Hailey looked stunning in short, white dress. They enjoyed local food, including an oyster roast,” the insider added.
Later in the evening, several friends also joined the families for bowling at the Boundary on the Montage property.
An insider close to Bieber recently told PEOPLE that their second ceremony will be very meaningful for them both.
“They are both beyond excited to celebrate with friends this weekend,” the insider said. “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 said. “Justin is doing much better. He keeps focusing on his music and seems excited about it.”
The insider added that after the pair tie the knot for a second time, they’ll be “taking a break” while they “enjoy a honeymoon.”
