NEWYou can now listen to Fox News articles! Riley Gaines and Simone Biles’ feud took a new twist on Sunday as an old social media post from the Olympic gymnast came to light. Biles, in a 2017 post, appeared to be thankful that men don’t compete in women’s gymnastics.

Simone's tweets quickly went viral, with over 40 million total views and tons of comments thanking her for her support.

Gaines, 25, has become one of the most outspoken critics of transgender girls and women competing in female sports in recent years.
