The “12 Years a Slave” star, who is up for Best Supporting Actress, looked stunning in a light blue silk georgette gown by Prada.
The 31-year-old told E! News host Ryan Seacrest, "It's a blue that reminds me of Nairobi, and so I wanted to have a little bit of home."
Sure enough, #Nairobiblue instantly started trending.
