(Houston, TX)-- The Houston area's own Olympic Gold-winning gymnast is evidently short enough to be mistaken for a child. A flight attendant thought 4-foot-8-inch Simone Biles was a child and offered her a coloring book on a recent flight. The 25-year-old Olympic champ shared the moment on Instagram. Biles says another flight attendant served her a mimosa, so it all worked out.
