( CNN ) -- To the wonderful array of characters and names in the `` Harry Potter '' universe -- Ron Weasley , Dolores Umbridge , Bellatrix Lestrange , Cornelius Fudge and He-Who-Must-Not-Be-Named -- add yet another getting a shot at the spotlight : Celestina Warbeck . Warbeck is n't a completely new character . In a note on Pottermore.com ( sign-up required ) , author J.K. Rowling mentions that the `` Singing Sorceress , '' as she is known , has made occasional off-stage appearances in the Potter books and in a `` Daily Prophet '' series done for the Potter fan club . But she gets a full profile , along with a performance of her hit `` You Stole My Cauldron but You Ca n't Have My Heart , '' on the Potter website . `` 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 . `` I always imagined her to resemble Shirley Bassey in both looks and style . '' Bassey is best known in America for singing the theme songs to the James Bond films `` Goldfinger , '' `` Diamonds Are Forever '' and `` Moonraker . '' Rowling said that the first name came from an old co-worker. `` 'Celestina ' was simply begging to be scooped up and attached to a glamorous witch , '' the author wrote . In the profile , Rowling describes Warbeck as a Welsh prodigy whose mother `` bombarded '' Hogwarts with letters to promote her daughter with various performing arts groups . She became a huge star . `` Three devoted fans were involved in a nasty three-broom pile up over Liverpool while trying to reach the last night of her 'Flighty Aphrodite ' tour , and her tickets often appear on the black market at vastly inflated prices , '' Rowling wrote . Warbeck is Molly Weasley 's favorite singer . Warbeck has eight homes , has been married three times and is capable of `` drown ( ing ) out a chorus of banshees . '' Her music can , of course , be heard at the Wizarding World of Harry Potter at Universal Orlando Resort .
