One celeb was noticeably absent from the Wilson's wedding activities: Serena Williams.

The tennis champ was said to be a bridesmaid at her BFF's wedding, however, she was forced to back out due to Wimbledon semi-finals match.

"Serena really wanted to be a part of Ciara's bridal party when she asked her a while back, but she knew work may conflict," a source shared with E! News.

"Ciara was understanding and knows Serena would be there if she could. They have spoken today and have FaceTimed each other, so it's like Serena is in the room with all the girls."

Congratulations to the happy bride and groom!
