Houstons best and brightest stars asking people to mask up in the fight against COVID-19. The most decorated World Champion in gymnastics and Olympic Gold Medalist, Simone Biles, and other big names were roped in as ambassadors in Houston Mayor Sylvester Turners Mask Up Houston campaign. Biles, along with Houston Astros Carlos Correa and rapper Slim Thug, who is also a COVID-19 survivor, are offering their resources to spread safety information to Houstonians. Turner tweeted multiple videos featuring the Houston stars encouraging people to wear masks.
