Developing a love for music at an early age, Joplin sang in her church choir as a child and showed some promise as a performer. She was an only child until the age of 6, when her sister, Laura, was born. Four years later, her brother, Michael, arrived. Joplin was a good student and fairly popular until around the age of 14, when some side effects of puberty started to kick in. She got acne and gained some weight.
