Just in case Serena Williams’ 23 Grand Slam tennis titles weren’t enough to tip you off to what a boss babe she is, the mommy-to-be has been showing off a whole new side to fans in recent weeks, offering up the perfect response to the inevitable red carpet gender questions and clapping back at racist remarks about her baby.

Now, she’s giving us (another) taste of her maternity style, serving up (pun intended) some Beyoncé-level sass in a ruffled black one-piece fit for a diva, with a series of Instagram shots posted to her page.

Looking happy and healthy, Williams basks in the sun’s rays as she holds the bump that is her growing little boy or girl. She also showed off her stunning engagement ring from fiancé Alexis Ohanian, adding a little *extra* shine to her pregnancy glow.

Her stint on the yacht appeared to be part of her bridal shower last weekend, which kicked off with a bang in Miami Florida.

As event planner Val Vogt told ET, “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 also dished the deets on some of the athlete’s festivities, saying, “There were constant surprises; from a painting party to unique bridal shower games to having a live fashion illustrator on the yacht.”

From the looks of things, girl nailed it.
