Little is known about Warbeck's early life. She probably completed her magical studies before becoming a singer.
Career as a singer
After becoming a singer, Warbeck became well-known in wizarding Great Britain, getting involved in important causes frequently. She protested against the Ministry of Magic's decision to restrict Hallowe'en celebrations, and recorded a version of the Puddlemere United Quidditch team's anthem, Beat Back Those Bludgers, Boys, and Chuck That Quaffle Here, to raise funds for St Mungo's Hospital for Magical Maladies and Injuries. She also featured heavily on shows at the Wizarding Wireless Network, one being the Witching Hour, hosted by Glenda Chittock.
Celestina is Molly Weasley's favourite singer. During Christmas, the Weasley family and their guests listened to a Christmas broadcast at the WWN, in which the musician sang tunes such as A Cauldron Full of Hot, Strong Love and You Charmed the Heart Right Out of Me. Despite Mrs. Weasley's enthusiasm, none of the other people at The Burrow seemed to pay much attention to the songs, except for Fleur Delacour, who despised them, as she was mimicing the lyrics and saying how horrible it was.
- A Cauldron Full of Hot, Strong Love
- You Charmed the Heart Right Out of Me
- Beat Back Those Bludgers, Boys, and Chuck That Quaffle Here
- You Stole My Cauldron but You Can't Have my Heart (album)
Celestina possibly comes from the word celestial, meaning "pertaining to the sky or visible heaven." Warbeck may come from warbler, which is a singing bird.
Behind the scenes
- Madam Warbeck usually performs with a chourus of banshees.
- Celestina's latest album was entitled You Stole My Cauldron but You Can't Have my Heart. The promotional tour included a show in Liverpool; fans desperate to arrive at this concert were involved in a three-broom crash.
- Warbeck scheduled concerts in Exmoor, sponsored by The Sorcerer's Saucepot. Tickets were on sale for five Galleons each, and fans had to book their Portkeys early.
