Gymnastics all-around champion
POCKET ROCKET: Little Gabrielle Douglas - aged 16 and only 4 foot 11 inches tall (150cm) - is the best in the world
America's Douglas was locked in a head-to-head battle with Russia's Viktoria Komova, but she edged her opponent into silver medal position. Another Russian, Aliya Mustafina, claimed bronze.
Douglas rocketed into an early lead on Vault. Then she showed why she was nicknamed 'The Flying Squirrel' on the Uneven Bars as she posted a strong score.
Mustafina saw her hopes of gold crumble after she fell off the Uneven Bars as Douglas shone, retaking the lead from Komova with only the Floor remaining.
Douglas produced a fantastic Floor performance to claim her second gold of the Games - after helping USA win the Team final.
She said: "I just wanted to go out there and show everyone what I was capable of.
"My coach has prepared me well. He told me my training will not go in vain. So there I was, just cruising and now I am on cloud nine."
