Jillian Michaels'The Biggest Loser' and 'Losing It With Jillian' trainer Jillian Michaels has not always been so confident about her physical self.

The 36-year-old fitness fanatic reveals in the new issue of Parade magazine's Healthy Style that she went under the knife to rid her face of a nose that was "the size of a softball" and subjected her to cruel ridicule in middle school.

Michaels, who has admitted many times that she was an overweight child, says she once weighed about 175 pounds when she decided to have rhinoplasty to reduce her nose in an attempt to stop the bullying.

Michaels shared a "before" pic from her teen years with the weekly, revealing a heavier face and a nose that is much more prominent than the one familiar to her television fans.

"Once I was sitting at lunch and got surrounded by a bunch of kids who let me have it about how ugly I was -- my unibrow, the size of my nose, the fat rolling over my jeans. It was pure hell. My mother had to pull me out and enroll me in another school," she tells the mag.

"I had my nose done," Michaels explains. "I felt much better about myself. Plastic surgery is a very personal decision."
