Stars Surprise Their Fans

To make Nicole's dream happen, The Oprah Show tracked down one of the hottest singing stars around. At age 17, Avril Lavigne's first album sold 15 million copies and had a host of Grammy nominations, but when the busy rocker heard about Nicole's wish, she signed up for an elaborate surprise: a private concert for Nicole and her classmates in their high school gym.

Only Nicole's high school principal was in on the secret. He covered up windows and posted signs to keep everyone out of the gym. Meanwhile, Avril snuck in the back door of the school...and Nicole and 780 classmates got the surprise of their lives.

Avril thanked all of Nicole's friends by singing "Complicated," "My Happy Ending" and "Skater Boy."
