Can an 'anti-star' exist?

Can a star made of the anti-matter counterparts to normal stars exist?

Can it exist? Yes, nothing about antimatter expressly forbids it from forming into a star.  However, there is no evidence that one does exist in our universe and the prevalence of matter makes it highly unlikely that it would be concentrated enough to form into a star let alone survive as one for any length of time.
