Atlanta-native Seacrest, 30, began his TV career as a correspondent on EXTRA: THE ENTERTAINMENT MAGAZINE and has been hosting American Idol since it's 2002 debut.
Cowell says, "(The star) is ill-deserved. I cannot believe April 20 is going to be Ryan Seacrest Day. I am officially taking this day off my diary.
"Other people doing well just naturally makes me unhappy. I am officially taking this day off my diary."
Seacrest's star was for his achievements in radio broadcasting, but he admitted he wasn't sure anyone would turn up to the unveiling.
He admits, "I thought this would be the most unpopular star dedication ever."21/04/2005 17:20
