TV presenters
Famous for: Their enduring onscreen double act
Between them, the inimitable Ant and Dec have become the kings of the small screen. Presenting such shows as Pop Idol and CD:UK, the pair picked up a Lifetime Achievement prize at the 2002 National Television Awards despite being only 27-years-old. Their joint fame doesn’t prevent people from getting them mixed up, however. For those who don't already know, Ant's the slightly taller one.
