The interior designer first teamed up with the media powerhouse in 2008, as the host of her philanthropy challenge show, Oprah's Big Give. But his partnership with Winfrey didn't end there: he landed his own syndicated show, The Nate Berkus Show. "We brought him here because of his incredible eye for style, and we grew to love him for his big ole heart," Winfrey said during his last appearance on her show. "He taught millions of us to love the way we live."
