The Duchess of Cambridge is one of only three Brits to appear in Time magazine's 100 most influential people in the world list.
Novelist Hilary Mantel and three-time Oscar winner Daniel Day-Lewis, who has both British and Irish citizenship, also made it on to the prestigious list along with the Duchess.
Kate is the only member of the Royal Family to be included in the top 100, which includes filmmaker Steven Spielberg, Beyonce and Jay Z.
Pakistani schoolgirl Malala Yousafzai, who was brought to the UK and treated in Birmingham after being shot in the head by the Taliban, also features.
The 15-year-old has set up education charity the Malala Fund and is now a pupil at Edgbaston High School for Girls.
Mario Balotelli, the Italian striker who called Britain home when he played for Manchester City, also made the list, as well as Oscar winner Jennifer Lawrence.
American President Barack Obama has made the list for the eighth time this year, with his wife Michelle featuring too.
Time managing editor Rick Stengel said:
This year we are trying something new: seven cover portraits of Time 100 honorees who reflect the breadth and depth of our list, each one profiled inside- as is our tradition- by an equally luminary voice.
We commissioned the renowned photographer Mark Seliger to create the covers. The shoots took him and his crew to Los Angeles, Miami, New York City, Washington and Birmingham, England, where he took the first formal portrait of Malala since she survived a vicious attack by the Taliban last October.
