Britain's royal baby Prince George has beaten One Direction singer Harry Styles and supermodel Cara Delevingne to be named London's most influential star.

The tot, who was born to Prince William and Catherine, Duchess of Cambridge in July (13), has been crowned the city's most influential person in the London Evening Standard's annual Power 1000 list.

The prince was reportedly chosen by the newspaper's bosses because he has become the capital's biggest tourist attraction in the three months since his birth.

Editor Sarah Sands says, "London is a magnet for the rest of the world and our newest power resident, Prince George, is a timely symbol. He is our greatest tourist attraction, along with his great-grandmother, which is why he has been chosen this year as the first among Londoners."

Five members of the royal family, including Catherine, Duchess of Cambridge, Princes William and Harry, and Queen Elizabeth Ii were joined by Styles and Delevingne in the top 20. Others in the list include London Mayor Boris Johnson and British Prime Minister David Cameron.
