“Look who I just met! I was so excited,” she gushed. “He was so Himself. I love this guy. #sterlingkbrown #thisisus.”
Winfrey was so ecstatic following the encounter -- which took place at a taping of Variety Studio: Actors on Actors presented by Shutterstock -- that she even made a cute collage of pics of the pair for the post.
Fortunately Brown was able to pull it together and share a more poised pic with the talk show queen. "When you're able to get it together enough to look like you're not in complete and utter shock that @oprah is a fan!" he wrote.
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.”
