Simone Biles is bringing the heat both on-and-off the gymnastics matt.

There's no disputing Biles's dominance in her field. 

She's the GOAT of the gymnastics world and the United States's most successful Olympic gymnast ever. 

At the same time, she's proving a powerful force away from the Olympic stadium, clapping back at a former teammate's criticism of the US's gold-medal-winning team.

Truth be told, it's a bit of a saga. 

I'll break it down for you the best I can. 

What happened between MyKayla and Simone?

Biles and Skinner have known each other for a long time. They were teammates at the Tokyo Olympics where Skinner won a silver medal on the vault, an event Biles pulled-out of with the 'twisties'. More on that here.  

Skinner retired immediately after Tokyo, while Biles went on to cement her place in history as the best gymnast ever seen.

After Team USA's win in the Paris Olympic women's gymnastics team final, Biles took the chance to celebrate, while also seemingly responding to criticism Skinner dished out in the weeks prior. 

Here's the post.
