Surly, yet somehow charming American Idol judge Simon Cowell will be a presenter at this Sunday's 58th Annual Primetime Emmy Awards. The brash Brit will also lead the telecast's special tribute to Dick Clark.

Clark, 76, is one of TV's longest-running and best-known personality. He has long been known for his continued youthful appearance, earning the moniker "America's Oldest Teenager," and also for his good health until he suffered a stroke in 2004.

Though known primarily for his blunt, sarcastic American Idol judging, the 46-year old Cowell achieved celebrity status on Pop Idol, the UK version of American Idol that spawned the U.S. version.

His production company, SYCO, also produces the award-winning X Factor, the No. 1 entertainment show in the U.K. While his non-compete clause prevents him from appearing on other shows, Cowell created and served as executive producer on America's Got Talent and the forthcoming Celebrity Duets.
