As well as enjoying a successful acting career, she's also become known for her work with the United Nations and starting up a feminist book club, Our Shared Shelf.

And Emma Watson, 26, chose a novel way to share the joys of one of her favourite books - the late Maya Angelou's Mom & Me & Mom - by hiding copies of the tome at different stations on the London tube network on Tuesday.

The actress filmed herself hiding copies of the novel - each with a handwritten note - along the escalator support beams at St John's Wood station, shortly before she was also spotted carrying out the task at Oxford Circus.

Novel! Emma Watson left copies of her favourite novel - May Angelou's Mom & Me & Mom - at different London tube stations as part of the Books on the Underground initiate on Tuesday

Taking to Faecbook soon afterwards, she announced: 'I've been hiding copies of Mom & Me & Mom for Books on the Underground on the tube today! See if you can find one tomorrow! #OurSharedShelf.' 

Emma's actions were part of the Books on the Underground campaign, which encourages people to read books on the tube - and share the ones they enjoy.

Books on the Underground director Cordelia Oxley said: 'The campaign with Emma Watson is perfect as it promotes her feminist book club Our Shared Shelf, and also reminds people to look around for a hidden book when they're on the tube!'= 

She added: 'It was Emma's idea to be a Book Fairy for the day, and I think she did an amazing job.' 

Sharing is caring: The books included handwritten notes from the actress, who recently started a feminist book club, called Our Shared Shelf

Special announcement: She later took to Facebook to share news of her secret book mission

In September, the star cheered the possibility of the US electing its first female President in Hillary Clinton during a conversation about gender equality. 

Her words came on the night that Edgar Ramirez questioned a 'macho' world that teaches boys to suppress emotions and dominate women.

The actors roused up a glitzy and high-powered crowd at the Museum of Modern Art in Manhattan to promote U.N. Women's HeForShe initiative to draw men into the fight for global gender equality.

Emma, the U.N. Women Global Goodwill Ambassador, drew whoops and cheers when she referenced the possibility of the former First Lady winning the US presidential elections.

The actress also celebrated the fact that Britain has a woman Prime Minister in Theresa May.

Japanese Prime Minister Shinzo Abe, Canadian Prime Minister Justin Trudeau and Finnish President Sauli Niinisto also spoke.

She was also guest of honour at the 71st Annual United Nations General Assembly earlier in the day, where she delivered a passionate speech to mark UN Women releasing its first HeForShe Impact 10X10X10 University Parity Report. 

The star, a staunch campaigner for the HeForShe campaign aiming to promote gender equality, took to the podium to discuss the new developments.

The new report explains the commitments made by 10 universities across the world to focus on gender equality on campus.

The universities, which include the University of Oxford in England, Sciences Po in Paris and Georgetown University in the United States, have pledged to take a zero-tolerance stance on sexual assault, to lose the gender gap in administration and academia, and to provide briefings on gender issues for faculty and students.
