Can Rihanna do ballet

I sawed her on pointe shoes in umbrella but her feet were wrong why to do it. she had to make the position of her feet better. i have been on pointe shoes for 5 months and my dance teacher taught me alot about pointe shoes. The music video for All American Girl. was like that too. Carrie Underwood was wearing pointe shoes. Her feet were WRONG! So the answer to that question is no. you should not be on pointe shoes without a permission of a Ballet teacher. you must get fitted for pointe shoes. you don't want to much gap and space inbetween. your shoes cant be big or small
