It is not known whether Sparks has been dieting, but she reportedly enlisted the help of a personal trainer whilst performing on tour with the Jonas Brothers. The 'Idol' star has never previously shown an interest in losing weight and during an interview with People Magazine in 2007 she said, "I learned that I'm not ever going to be a size 2. I would look so weird as a size 2. Somebody would blow and I would fall right over. It just wouldn't be healthy". Back in November 2008, Sparks teamed up with the clothing label 'Wet Seal' to release her own 'plus size' line of holiday dresses and she has also worked as plus size model.
Since becoming the youngest ever winner of American Idol, Jordin Sparks has become a multi-million selling recording artist. Her self-titled debut album has gone platinum in the U.S and she was nominated for a Grammy Award in 2009.
