Just over a week after a romantic baby moon with fiancé and Reddit co-founder Alexis Ohanian saw the mom-to-be flaunting her growing bump in a flirty black ruffled one-piece, the legendary athlete proved that she is still in a vacation state of mind as she opted for a colorful kaftan during the Formula One event. Posing alongside Chris Hemsworth as well as a few racing drivers, the pro tennis player sported a curve-skimming zebra-printed number, which featured bright dashes of lime green, yellow, purple, and red accentuating the intricate design. Opting to ring in the long weekend with summer-perfect beauty, Williams paired the bold print with natural makeup and beachy waves, and topped off the ensemble with a pair of black bow flats.
