(USA TODAY) -- J.K. Rowling is giving fans more new writing from the world of Harry Potter.
On her website, Pottermore.com, Rowling has penned a tale of lesser-known character Celestina Warbeck. Or as Rowling puts it: She's an "off-stage" character.
She tells NBC's Today show that Warbeck is a warbler who would most look like 1950s singer Shirley Bassey.
"Celestina Warbeck is one of my favourite 'off-stage' characters in the Harry Potter series, and has been part of the Potter world ever since its inception, making an early appearance in the short-lived 'Daily Prophet' series I produced for members of the equally short-lived fan club run by my British publisher, Bloomsbury. Although we never lay eyes on Celestina during the whole seven volumes of the Potter books, I always imagined her to resemble Shirley Bassey in both looks and style. 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."
Here are some of the details of the character:
Birthday: Aug. 18
Wand: Larch and phoenix feather, 10 1/2 inches long, flexible
Hogwarts House: Gryffindor
Special abilities: Ability to drown out a chorus of banshees, tap-dancing, fancy baking
Parentage: Wizard father, Muggle mother
Family: Has married three times; one son
Hobbies: Traveling in fabulous style, breeding rough-coated Crups, relaxing in any of her eight homes
