WATCH: Academy Award winners Lupita Nyong'o and Common were among the celebrities who gathered last week in Washington, D.C., to celebrate the opening of the National Museum of African American History and Culture.
Nyong'o, whose dress from "12 Years a Slave" is on display at the museum, praised the venue at a junket before seeing the museum for herself. She told Circa, "It's invaluable to have that kind of home for this history, and for people to be able to go in and interact and learn in an immersive way."
Nyong'o joined the celebration Saturday, when the museum opened to the public.
At an affiliated event Friday, Common reflected on a rap career that began when he was just 12.
"It was just one of those things where God taps you on the shoulder ... and you don't know that it's part of your path, but it is," he told Circa. "And now, that rap, finding my voice in that way, has allowed me to be here in one of the most monumental times in American history."
Among the many celebrities and dignitaries joining Presidents Barack Obama and George W. Bush at Saturday's opening ceremony were Oprah Winfrey, Will Smith, Ava Duvernay, Shonda Rhimes, Dave Chappelle, Samuel L. Jackson, Colin Powell, Tom Hanks, Henry Louis Gates and Jesse Williams.
