'HP' Stars Wish J.K. Rowling A Happy Birthday

As if Potterheads needed another reason to adore Harry Potter, its author, and the actors who brought some of the most influential and inspiring literary characters to life. For those who don't know or need a reminder, July 31 is J.K. Rowling's birthday, and she happens to share birthdays with Harry Potter (FYI, Harry is now 35... WHOA). This Friday, Rowling turned 50. Happy Birthday, J.K.! To celebrate the author, a handful of Harry Potter stars wished Rowling a happy birthday with some truly magical messages. All of this came to be thanks to TIME asking the co-stars to write personal messages for Rowling. And yes, they're as amazing as you'd expect.

From the beloved Ron Weasley to my favorite Severus Snape to the loathed Dolores Umbridge (ahem!) to Neville Longbottom, many Harry Potter stars are sending their love to the author. In addition to wishing her all kinds of magical goodness on her special day, they thank her for creating the characters who made most of them famous and even got children exciting about reading.

Rowling is one empowering woman, and I, personally, thank her for bringing the world of wizards and witches to life. Can you imagine this world without Harry Potter? Me either.

With that said, check out a few of the sweet birthday messages the actors shared with TIME below.

Rupert Grint Aka Ron Weasley

"Wishing you a very Happy Birthday on your special day!"

Alan Rickman Aka Severus Snape

"The Happiest of Birthdays, Jo. A breeze for the supreme Time-traveller."

Robbie Coltrane Aka Hagrid

"You don't look a day over 40; everyone knows what a wonderful author you are, and how much you did to get children to read books, and your charity work, but they perhaps don't know that in private you are very very funny."

Matthew Lewis Aka Neville Longbottom

"I would like to thank Jo for changing MY life. Without her imagination and her talent I would never have become the man I am today."

Oliver Phelps Aka George Weasley

"Have an amazing day & watch out for any 'Puking Pastilles.'"

James Phelps Aka Fred Weasley

"Happy Birthday Jo, I hope you have a great day. Mischief managed."

Jason Isaacs Aka Lucius Malfoy

"To the woman who has made half the world feel less alone, afraid and in the dark; may the light you continue to shine always bounce back with interest."

Evanna Lynch Aka Luna Lovegood

"You inspire me endlessly in your art, your activism and your sassy Twitter comebacks so please keep loving and caring and imagining as hard as you do."
