Justin Bieber and Hailey Baldwin tied the knot at a courthouse by themselves back in September, but the couple has always been reported to be planning a second, religious wedding for their family and friends. From their multiple postponements to the possible guestlist, here's everything that we know about the forthcoming Bieber–Baldwin celebration so far.

Baldwin and Bieber are considering a destination wedding.

Bieber and Baldwin are looking to have their religious wedding ceremony and reception with friends and family somewhere tropical. "Justin and Hailey both love tropical destinations. They are currently looking into options for a tropical wedding," a source told People. “Hailey is working closely with their planner and figuring everything out. She is very excited to plan her wedding.”

We've seen proof that Bieber loves a tropical spot. The couple's friend Kylie Jenner went on an island trip to celebrate her daughter Stormi's first birthday, and Justin jokingly requested an invite for him and Baldwin to join them. Jenner promised that there would be space next time for the "love birds."

The wedding might happen in September, close to their one-year anniversary date.

The Biebers originally wanted to have their wedding in January. According to Page Six, the pair later sent out Save the Date invitations for February 28, the day before Justin's 25th birthday. In January, a source told People that the date had been pushed once more: “It seems it will happen in April, or May instead."

Now, after postponing the ceremony for the third time, Bieber and Baldwin are thinking about having their religious wedding later in the year—in the fall, so that it falls a little closer to their actual anniversary. “They have talked about possibly having their wedding closer to their one-year marriage anniversary date in September,” an insider told Us Weekly.

Even though there have been multiple postponements, the Biebers have everyone's best interest in mind. “They’re working with the schedules of all their friends and family to make sure they can be surrounded by the people they love. There’s no real rush. They’re already legally married, but they’re very excited about throwing a celebration with their loved ones,” the Bieber source shared.

Perhaps the biggest reason for the wedding postponements is that Baldwin wants to be mindful and supportive of Bieber's mental health issues, and doesn't want the added pressure of a wedding to stress him out. Bieber started seeking treatment for depression in February, and in March, a source close to the couple told People they "will still have a wedding eventually, but this is not their focus right now. They haven’t sent out any new Save the Dates. They will wait until Justin feels better and is excited about planning their wedding again.”

Baldwin's main focus at the moment is trying to be as supportive as she can to her husband. "She’s not dealing with her own issues, so she can give so much to Justin and be here for him," a source told Us. "He feels very safe with her. They love working out together and being able to focus on health." A People source also confirmed that health comes before their wedding: "Hailey keeps supporting him. They will still have a wedding when they feel they are ready,” the source said. “The most important thing for them is that Justin is mentally healthy.”

Some of Baldwin's bridal party members have been confirmed.

Kim Basinger, Baldwin's aunt, let it slip back in July that the bride had officially picked out her bridal party members. Baldwin's sister Alaia and her cousin Ireland were confirmed by her aunt to be part of the wedding party.

"Oh, it’ll be fun," Basinger told US Weekly. "Alaia and Ireland, they’re in the wedding. So believe me, I just—it’s cool! I think it’s sweet. It’s a very sweet thing. Happiness…We’re living in some really dire times right now."

There will be about 300 guests.

TMZ reported that 300 people were sent Save the Dates back when the ceremony was set to take place on February 28. Among those who received invitations were Drake, Chris Brown, Odell Beckham Jr., Kylie Jenner, and Travis Scott—which makes it seem likely that a few more Kardashians will end up attending.

Baldwin doesn't have a wedding dress yet.

The model told The Cut back in September that her dress has yet to be made, but she has settled on a designer, who will be kept secret.
