Claudia Sulewski has shared why Billie Eilish had such a special job at her wedding to Finneas O’Connell.
Finneas and Claudia got married in California on August 29 so when they started planning the wedding, Billie was the first person they called.
Both of them wanted Billie to be part of their wedding in a big way. Finneas wanted Billie to be his best man as Claudia wanted her to be her maid of honourr.
So they came up with a simple answer. Billie would marry them.
Claudia explained the story in a video on YouTube.
She said, “He wanted her to be his best man, and I wanted her to be my maid of honor. So we thought, ‘Okay, sounds like she needs to marry us.’”
Claudia also said that Billie doing this for them was “the greatest gift she could ever give us.”
The Bad Guy hitmaker also sang Birds of a Feather at the wedding party.
Claudia said she is still very emotional about the day, adding that the music from the wedding still makes her cry.
The couple first met on dating app Raya in 2018 and Finneas proposed to Claudia last September after seven years together.
Now, Claudia says she would happily live the wedding day all over again and cannot wait to spend the rest of her life with Finneas.
