J.K. Rowling Just Wrote A New Biography About A Harry Potter Character

Harry Potter is clearly on J.K. Rowling's mind these days, and that's just as well as she's penning the screenplay for the anticipated Fantastic Beasts trilogy. But it isn't Hippogriffs and Hinkypunks that she's written about most recently. It's the sensational singer Celestina Warbeck.

Fans of the Harry Potter books will likely recognize Celestina Warbeck as Molly Weasley's favorite singer. She brought the wizarding world "A Cauldron Full of Hot, Strong Love" and "You Charmed the Heart Right Out of Me." This week, in honor of Celestina's birthday (August 18), J.K. Rowling penned a brief biography about the singer. The entry was inserted in the "Floo Powder" chapter of the Pottermore.com, and gives us some background information into who Celestina Warbeck is.

For those who only know the movies or are casual fans of the books, Celestina Warbeck never appears in the story, but Molly Weasley is known to be a fan of the singer. In Harry Potter and the Half-Blood Prince, she blasts "Hot, Strong Love" from her wooden wireless when the Weasleys & friends are gathered for the holidays. Rowlings biography of the singer can be read in its entirety at Pottermore.com, or -- if you aren't registered at the Harry Potter site -- over at Today.com.

Among the things we learned from the bio, Ms. Warbeck was born to a wizard father and a Muggle mother, the latter of whom was a stage performer, who met Celestina's father when she was attacked by a Lethifold disguised as a stage curtain. For information on the fairly horrifying description of a Lethifold -- it's basically a blanket that eats you -- see Page 25 of Fantastic Beasts and Where To Find Them.

Celestina Warbeck, who would later be known as the Singing Sorceress, attended Hogwarts and was in the Gryffindor House. While Molly Weasley is a huge fan of Warbeck's, she's never seen the singer live, and it sounds like high ticket costs and ridiculous black market prices for the singer's concerts may be the cause of that. Warbeck has been married three times.

J.K. Rowling says she always imagined Celestina Warbeck resembled Shirley Bassey, both in looks and style. "I stole her first name from a friend with whom I worked, years ago, at Amnesty International's Headquarters in London," Rowling said. "'Celestina' was simply begging to be scooped up and attached to a glamorous witch."

The fictional singer is represented at The Wizarding World of Harry Potter in Diagon Alley. Someone should probably inform Molly Weasley.

This isn't the first time this summer that J.K. Rowling has taken to the quill to fill in a few blanks in her Harry Potter universe. Last month, she wrote an article from the voice of the gossip-loving Rita Skeeter, updating us on the lives of some of Dumbledore's Army. While Celestina Warbeck's path may never have crossed with Harry Potter, it's still great to get to know her better. And who knows, if the Fantastic Beasts movie ends up overlapping with Ms. Warbeck's era -- or her parents! -- perhaps she'll be in the new movies.
