In an exclusive YouTube video released shortly after the event, Sulewski reflected on the planning process and the unique decision to have Billie Eilish, Finneas’ sister, officiate their wedding. Initially, both Sulewski and O’Connell had hoped to include Eilish in their wedding party; O’Connell wished for her to be his best man, while Sulewski envisioned her as her maid of honour. “We thought, ‘Okay, sounds like she needs to marry us,’” Sulewski shared with her audience. This arrangement, she expressed, turned out to be “the greatest gift” they could have received.
The couple decided on an outdoor setting for their ceremony, choosing to keep the affair intimate by opting against traditional bridal parties. Sulewski explained that this decision helped create a more personal atmosphere, allowing them to fully immerse themselves in the moment. Among the guests were Justin and Hailey Bieber, Kristen Bell, and Dax Shepard, all gathered to celebrate the union of the newlyweds.
Eilish not only officiated the wedding but also performed during the reception, treating attendees to a rendition of her song “Birds of a Feather.” In a heartfelt moment prior to the wedding, she had offered her support during Sulewski’s final dress fitting at the Oscar de la Renta boutique in Beverly Hills, expressing her excitement at seeing her sister-in-law in the stunning gown. “Oh, my God, I can’t believe it. You look stunning. You look like an angel,” Eilish exclaimed, showcasing the bond between the two women.
Following the ceremony, Sulewski opened up about her feelings towards the wedding, candidly stating that she was “still on cloud nine” and overwhelmed with emotion. Any music reminiscent of the day evoked tears as memories flooded back. She described the day as “the most beautiful, special, intimate” experience she could have imagined, full of emotions that ranged from euphoria to calmness. It was, she insisted, a day steeped in love and joy that elicited a newfound understanding of happiness.
Sulewski went on to express her desire to relive the day if given the chance, calling it the “best day of our life.” Despite joking about the potential challenges of parenthood, she declared her commitment to O’Connell and her excitement about their future together. The couple had first crossed paths through a dating app, Raya, back in September 2018, and their relationship blossomed rapidly.
Reflecting on their early days together during a podcast interview, Sulewski recalled the immediate connection they shared—“We fell for each other so hard and so fast and so honestly.” Their relationship blossomed without any pretence, revealing an authentic bond that resonated strongly from the start.
Seven years later, the couple decided to take their relationship to the next level, with O’Connell proposing on 22 September 2025. The engagement announcement, shared via a joint Instagram post shortly thereafter, featured romantic photographs that captured the essence of the moment. Sulewski joyfully remarked in the caption, “forever and ever 9.22,” encapsulating the excitement and commitment they felt at that milestone.
As they embark on this new chapter together, Sulewski and O’Connell exemplify the beauty of love and partnership, with their wedding day marking a significant milestone in their evolving journey. Fans and followers alike are eager to witness the couple’s next adventures, as they continue to navigate life hand in hand.
