Baby Boy

Baseball commissioner Bowie Kuhn put this name in play as a first name, but David Bowie (born with the considerably less marketable moniker of David Robert Jones) dyed it blond and gave it charisma. He changed his surname in 1965 to avoid confusion with the then popular Davy Jones of The Monkees, and especially since his death, his admirers have seen it as an increasingly viable baby name namesake.

Jude is a modern star, maintaining a steady level of popularity -- but not TOO much popularity -- for more than a decade now. Thank Jude Law and the great Lennon-McCartney song "Hey Jude", double-handedly responsible for propelling Jude up the charts.

Knox is an old Scottish surname that Brad Pitt (whose great-great-grandfather was named Hal Knox Hillhouse) and Angelina Jolie took out of the back cupboard, dusted off, and elevated to coolness--to the point where it entered the popular baby names list in 2009. Knox now ranks among the most influential celebrity baby names.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.
