Serena Williams was said to be Ciara's bridesmaid, but had to back out due to Wimbledon's semi-finals.
"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 told 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."
