Serena Williams, a tennis champion, has posed in a swimsuit again following backlash over her use of weight loss medication, Ro. She was pictured wearing an olive green one-piece swimsuit and a pair of Ugg slippers. This follows a previous controversy over a joint video showing her seemingly injecting herself with the medication, which she claimed she needed after having two daughters with husband Alexis Ohanian. The four-time Olympic gold medalist previously revealed her weight transformation in a yellow cutout swimsuit.
