Kelly Clarkson is probably the most successful and well-known American Idol winner. But her road to stardom wasn’t easy. She may have the voice and talent to make chart-topping songs but she was ridiculed for her weight. She wasn’t meeting Hollywood’s standard. But despite that, she had a string of successful singles, albums, and even won several awards. In 2004, she drastically lost weight with a strict diet and fitness program. She was almost unrecognizable. But after giving birth, she returned to her more generous proportions which she doesn’t mind at all.
