Hello ( имя певца ). My name is ( твое имя ). I'm your fan. Your songs ( можешь пречислить песни ) are great! I listen to them every day. I read a lot about you. You are a very interesting person. If you will be giving a concert in our city, I'll take you an autograph. Oh! I almost forgot! I have a lot of posters with you! I look forward to you in ( твой город ). With best wishes ( твое имя )
Ну думаю как - то так. Точно не уверена.
