The Harry Potter cast sticks together.
Emma Watson talked to ET's Carly Steel at the Hollywood premiere of Beauty and the Beast
, where the Hogwarts alum shared that she and her co-stars from the movie series still keep in touch -- only they've traded messenger owls for messaging apps!
"We actually have a group WhatsApp which invited everyone really from the main cast from Harry Potter to come to the screening," the 26-year-old actress revealed. "It's a case of trying to, like, get people into the right places, but yeah, everyone has been very supportive and I'm very supported by my old co-stars."
Watson also explained that while there are certainly parallels between Harry Potter and Beauty and the Beast -- two beloved works brought to life in live-action -- childhood afforded her certain blinders to the pressure that she didn't have this time around.
"Playing Hermione when I was a child ... was kind of an 'ignorance is bliss' factor a little bit," she reasoned. "Now as an adult, I knew i was bringing to life ... part of people's childhoods, and I kind of knew what that was."
One big sense of nervousness for Watson -- singing as Belle!
"I was convinced that I was Florence Foster Jenkins, like, I was a terrible singer, but no one could tell me that I was very bad. This was my major, major fear," she confessed. "It took me, like, six months to get over and then I think, like, finally halfway through the movie I finally was like, 'Maybe, I'm OK.'"
"People seem pretty convinced by me, so I'm going to go with that," she added. "It took some conversations with myself in the mirror a few mornings."
Now that she's branched out into a singing role, we also asked Watson whether she'd consider branching out further into comedic acting (to her credit, she does have a cameo in Seth Rogen's 2013 film, This Is the End).
"People are surprised in real life that I'm really silly," she shared. "People think I'm super serious, then I can be like, 'No.'"
