Azerbaijan and Greece announced professional dance couples as their representatives at the Eurovision Dance Contest 2008. According to the regulations of the contest, professional couples were not allowed to take part in the competition. The EBU specified that the couple had to be composed of one professional (defined as a dancer who earns his or her living through dance and dance-related activities), and one non-professional known in a field other than dance. The non-professional was not required to be a celebrity, as long as he or she was known in his field, and it was also not a requirement that the non-professional had no dance experience. Since the representatives for Azerbaijan and Greece both consisted of two professional dancers, however, it is not clear why their entries were considered valid.
