And the Greenleaf star is definitely used to leaving celebrities starstruck. In fact, the actress’ A Wrinkle in Time co-star Reese Witherspoon recently shared how Winfrey would have cast and crew hypnotized in the make-up room during filming in New Zealand.

“She’d be like, 'You know what book I really love?' and everybody gets silent,” Witherspoon told Conan. “Like, pull out a pen. 'You know what the most important thing I ever learned in my life?' and everybody's like, you could hear a pin drop.”
