In honor of B Mack's birthday today, after years of him doing musical tributes to Karly, it felt like it was time to bust a rhyme for him! With the help of Karly's boyfriend, Matthew (who used to be a rapper / producer) we proudly present this hot track "B Without the Mack". ЁЯОдЁЯОзЁЯФе Happy Birthday, B Mack!
