Emma Watson hit the streets of New York City to honor this year's International Women's Day.
The "Beauty and the Beast" star and gender rights activist, in partnership with Book Fairies, visited multiple historic sights on Wednesday with one mission in mind: To celebrate the social, economic, cultural and political achievements of women through the power of literature by leaving signed books throughout the city.
Watson documented her day on Twitter, writing, "Today I'm a red-striking ninja book-fairy out to spread some wise women's words," before heading out to the Harriet Tubman Memorial, the Joan of Arc Memorial, the Gertrude Stein statue and the Eleanor Roosevelt Monument.
The 26-year-old British actress wrote personal messages in each of the books, including a copy of Alice Walker's "The Color Purple," which are all a part of her feminist book club.
One lucky recipient posted a photo of Watson's handwritten note on Twitter, which read in part, "Congratulations on finding one! I hope you enjoy this book, and I'd encourage you, when finished to leave it somewhere for the next person to find."
Watson remained mostly undercover throughout International Women's Day but made time for a fan who spotted the celeb outside Blue Stockings Bookstore. In a separate video, the fan, clearly starstruck to see Emma placing books on a nearby bench, embraces the Harry Potter alum with a sweet hug.
Other celebrities who recognized International Women's Day included Britney Spears, Adele, Ellen DeGeneres and Serena Williams.
