Kelly Clarkson: I Haven't Changed Since 'American Idol'!

Kelly Clarkson is all smiles as she arrives at the ITV Studios on Wednesday (December 5) in London, England.

The 30-year-old singer is in town promoting her greatest hits album Greatest Hits – Chapter One, currently in stores.

While in London, Kelly gave an interview to the BBC where she declared that she has not changed one bit since her pre-American Idol days.

“I’m like, completely the same!” Kelly said. “I still show up in curlers…lookin’ like a hot mess for rehearsals. I’m like ‘it’s rehearsals!’ I’m the same girl.”
