Gabby Douglas is probably one of the most successful gymnasts of our time. She's only 21 years old, but her stellar performance in the Olympics have cemented her legacy as a gifted athlete.

Needless to say, she is very well-respected in her given field. How much has Gabby Douglas been able to actually make off of her work in Olympic gymnastics?
