Simone Biles is "all gas no breaks" – her words, not ours. The 23-year-old gymnast, now the world's most-decorated, updated her Instagram on Tuesday with a massive va-va-voom as she pumped gas into her swanky Mercedes-Benz G-Wagon. Simone, followed by 3.9 million, was out to show her fun side, but with a loose knitted jacket falling off the gymnast's shoulders and only a skimpy tube top underneath, the killer body was getting shown. Simone took under 15 minutes to be called a "bad-ss." Check out why below.
