A row is going on in Brazil over a decision to let a seven-year-old perform in the famous Rio Carnival.
Julia has been picked by her Samba School to lead the group as their queen in the parade.
But some people think that she shouldn't be performing because that role is normally given to a much older person.
Now a judge will decide next week whether someone so young can perform as a queen in the Carnival.
Julia's dad said she was a natural dancer and would be able to cope in the heat.
