Fans of the Harry Potter series will be happy to know that J.K. Rowling has brought to life another lesser-known character from the Harry Potter world of wizardry.

On Monday, Rowling published a piece about the story behind Celestina Warbeck, the character who Rowling describes as a ‘Singing Sorceress’.

The character of Warbeck, was never really mentioned in the Harry Potter books, except as Ron Weasley’s mom’s favorite singer. In the Harry Potter and the Half-blood Prince, Mrs. Weasley would get her radio out for the Christmas broadcast while waiting for Warbeck to come on air to sing:

‘Oh, come and stir my couldron

And if you do it right

I’ll boil you up some hot strong love

To keep you warm tonight.’

The published piece in Pottermore.com gives insight to the personal life of Warbeck, her humble half-Muggle origins and her blockbuster music career. Rowling tells us about how Warbeck likes traveling in fabulous style and how her [Warbeck’s] personal life has provided much fodder for the gossip columns of the Daily Prophet.

“Celestina is one of my (favorite) ‘off-stage’ characters in the whole series, and has been part of the Potter world ever since its inception,” Rowling wrote in Pottermore.com. “I always imagined her to resemble Shirley Bassey in both looks and style.”

As for the origin of the character’s name, Rowling wrote: “I stole her first name from a friend with whom I worked, years ago, at Amnesty International’s Headquarters in London; ‘Celestina’ was simply begging to be scooped up and attached to a glamorous witch.”

Die-hard fans of the books and movie franchise satisfy their hunger for new developments from Hogwarts through Pottermore.com. Rowling uses the website to publish additional installments that tell of how Potter, Weasley, Granger and friends have fared beyond the Deathly Hollows. In July, Rowling also published a piece on the life of the adult Potter as he turned 34 years old, as reported by gossip Rita Skeeter.  The full track of Warbeck’s single You Stole My Cauldron but You Can’t Have My Heart is also available for streaming from the website.
