She provided the voice of a woman at the party in "Ladies' Night".
An interview released prior to the first season has Marina Sirtis reporting that she was playing a "Greek prostitute". In a deleted scene at The Wheelhouse, Holt introduces "Athena", another prostitute date with whom Arianna is able to converse. Athena's speaking roles were removed and her only scene is at the end of "Ladies' Night" when Cleveland convinces Donna's Friends that he is cheating on her.
