Getting a compliment out of Simon Cowell is difficult. But young singer and proud carrier of Bieber fever Drew Ryniewicz really impressed this music industry veteran on tonight's 'X Factor.'

Ryniewicz first caught the eyes of the judges when she performed her very own version of Justin Bieber's 'Baby.' A bold move, considering L.A. Reid helped to launch the career of the Biebs.

Performing a silky smooth version of Roxette's 'It Must Have Been Love' in a kelly green dress perfectly suited for her age, Ryniewicz blew away Cowell. The sometimes crotchety Cowell seemed mesmerized by this youthful but oh-so-grown up performance. While we could really see that her voice does need some coaching, the possibilities seem endless for young Drew Ryniewicz.

When Ryniewicz finished, Cowell remarked that she was amazing, but she may be too young still. While she may need to grow into her voice, we think if she keeps at it, she could do big things -- winner of 'X Factor' or not.
