Williams, along with 20 of her closest friends and family, including her mom, Oracene, and sisters Venus, Lyn and Isha, checked into the 1 Hotel & Homes South Beach, where they enjoyed a little R&R -- and tons of fun surprises.
Event planner Val Vogt of The VLV Group tells ET that each detail of the bridal shower weekend was meticulously planned out.
"Serena is one of my best friends, so a lot of love and thought went into planning the magical detail-oriented bridal shower weekend," she revealed. "There were constant surprises; from a painting party to unique bridal shower games to having a live fashion illustrator on the yacht."
"Serena looked stunning and radiated happiness the entire time," Vogt added. "She was surrounded by so much love and amazing company!"
