Kelly Clarkson and Many More Stars Support Simon Cowell at His Hollywood Star Ceremony

Simon Cowell's Hollywood Walk of Fame ceremony brought out some of music's biggest stars on Wednesday. The producer was surrounded by family, friends, and colleagues as he was honored with a star in LA. In addition to posing with his wife Lauren Silverman, their 4-year-old son Eric, and Lauren's son Adam from her past marriage, the America's Got Talent judge had a reunion with some of his past American Idol and X-Factor contestants, including Adam Lambert, Louis Tomlinson, and Leona Lewis. Kelly Clarkson, who won the very first season of American Idol, even gave a speech during the ceremony gushing about how Simon changed her life.

"I said yes right away because I was so excited to be here for this, because literally we were right here 16-years ago when this man helped change my life," the Grammy-winning singer said. Kelly also spoke to Simon's ability to find "authentic people that have a raw talent and are really themselves and that's all they really know how to be and I think that is something that should be applauded and praised, in this industry especially." How sweet! See which other musicians popped up for the star-studded ceremony ahead.
