The tennis superstar posed in a light blue bikini top and floral bottoms in front of a mirror, proclaiming to her followers, “Who about to get in the pool? It’s me.”
In another clip, she swayed while recording on her phone, noting, “I need a lesson on how to do that like selfie face, I’m not good at that.”

In other clips, Williams – Sport’s Illustrated‘s Sportsperson of the Year – splashed around with friends in a pool and hot tub.
“After a long day at work, who is in the hot tub? It’s us!” she proclaimed.
Later Snapchat videos showed a growing number of guests arriving for the pool party, as Williams laughed and goofed around.
Williams regularly promotes body confidence, and told Good Morning America last year that she’s “learned to love me.”
“I love that I’m a full woman and I am strong, and I’m powerful, and I’m beautiful at the same time, and there’s nothing wrong like that. It’s so important to look at the positives, if I get caught up looking at the negatives it can really bring you down.”
