AceShowbiz - Justin Bieber and Hailey Baldwin are finally going to throw a wedding celebration, a year after they secretly tied the knot. The pair, who said their "I do" at a New York courthouse last fall, are reportedly planning a wedding party for next month.

"They decided in May that they would get married in September, so they have been planning for a while," a source tells PEOPLE. While a date has not been set yet, they seem to be meaning it this time as the source says that "Halsey works with a planner."

"They are trying to keep the wedding details quiet, but both seem very excited," the source goes on sharing. "They are very happy about their married life together."

Reporting a similar story, TMZ claims that the Canadian pop star and the American model are going to send out invites in a week.

Justin and Hailey were reported wanting a religious ceremony and celebration with family and friends after their secret courthouse nuptials last fall. However, they put off the plan while the "Baby" singer was dealing with a mental health issue.

"They've talked about possibly having their wedding closer to the anniversary of their marriage, in September," a source told Us Weekly in June. The source added though that their real priority at that point was Justin's mental health. The 25-year-old has been seeking treatment for depression since February this year.

"She's not dealing with her own issues, so she can give so much to Justin and be here for him," a source said. "He feels very safe with her. They love working out together and being able to focus on health."

Sharing her vision of a dream wedding, Hailey told The Cut in a September 2018 interview, "I just picture lights strung everywhere. I think having it in the woods would be so beautiful. My sister will be my bridesmaid. I was hers and maybe Justin’s little sister as a flower girl."
