Harry Potter fans will always hold Emma Watson in their hearts because she played Hermione Granger. After the franchise concluded, with Harry Potter and the Deathly Hallows - Part 2, there would be more opportunities for the Paris-born actress.

She would lend her voice to the role of Princess Pea from The Tale of Despereaux, play a high school senior, Sam, in The Perks of Being a Wallflower, and become the iconic Disney Princess, Belle, in the live-action version of Beauty and the Beast. Outside of her acting, she has become a model and activist. She's also received a degree in English literature.

Throughout her journey, she has made many great friends, who may just be friends for a lifetime. Whether these friends worked with her on film sets or not, there's no doubt that she cares about them. Here are 15 surprising celebs Emma Watson is close to.

15 Taylor Swift

Emma and Taylor, pictured with their other friends, are known for their gender equality activism. So, it's no surprise that these two are close.

When Emma discussed an important moment in her recent film, Little Women, she compared that scene to Taylor's battle with ownership over her music. She told Variety, “It’s about believing in yourself and knowing your worth and owning your worth."

14 Justin Trudeau

Canadian Prime Minister, Justin Trudeau, might not exactly be seen as a typical celebrity since he's a politician. However, he is well-known and, while working with Emma for a common goal. he built a great relationship with her. She has praised the prime minister for working hard to bring gender equality. Trudeau's cabinet is gender-equal. While these two will not always see eye to eye, they share strong beliefs.

13 Sophie Sumner

Considering that Emma and Sophie both met at the all-girls Headington School, these two English ladies certainly have a strong relationship that blossomed throughout the years. They also were roommates and Sophie commented on her friendship with Emma, telling Vogue, "I'm really lucky to have someone who understands it all."

12 Yusra Mardini

Emma is simply one of the kindest celebrities one can admire. In 2016, she met the Syrian Olympic swimmer, Yusra Mardini, and took the time on Instagram to tell her story.

They might not always have the time to meet and hang out, but there's no doubt that these two will always have an unbreakable bond, due to fighting for world peace and speaking out about their struggles.

Since Joseph and Emma presented an award at the Oscars together and showed so much charisma, it's hard to deny that these two are close.

Fans were loving every second of their time together, and we would not mind them working together again.

9 Kaya Scodelario

There is not a lot known about Emma and Kaya's friendship, but it is a given that they have a respectable bond. The two were seen hanging out at Gourmet Burger Kitchen in London, with Emma giving Kaya a friendly kiss on the cheek.
