Her face is her money maker...why would she fight bare knuckle and allow the possibility for far more facial cuts then she would ever receive in mma 
She is cute, but there are 100,000 equally cute girls on instagram that aren't small size, she is too small to model, her one skill she has worked on is fighting and the reason she got the contract was because she can fight and has the face. Hopefully it inspires other cutes who aren't hot enough to make it just modelling to take up combat. This is the best thing she can do with her face, other than marry rich, just think about it, her looks aren't 1 in a million, just top 20%.
