James Corden, 38
The British-born star of CBS’s The Late Late Show With James Corden catapulted to fame this year with the runaway success of “Carpool Karaoke,” the addictive, happy-making series that features him driving around with A-list celebrities and musicians and singing along to their hits or favorite songs. His episode with Michelle Obama has garnered 43 million views. No wonder Apple bought the rights to the series. (While Corden is unlikely to star in the Apple shows, he will serve as producer.) As for his TV show? It just won two Emmys.
