She has also acted on TV shows, including "Hart of Dixie" and "Bones."
Maroney recently spoke out about the abuse she endured as a gymnast in an Instagram post, comparing her experience with Britney Spears' fight to end her controversial conservatorship.
She said: "Britney's story resonates with me so much because just like Britney, I also had to 'fake it till you make it' to survive my 2012 Olympics. I was just trying to accomplish my dream, but I had abuse coming at me from many angles that I didn't understand how to process at 15. I had to suppress it, and I had to minimize it, just to get through the day."
