The `I Dreamed a Dream` hitmaker unveiled her likeness - which cost £150,000 to create - on 18.04.11 in the British seaside resort of Blackpool, North West England.
With every detail of the 50-year-old star encapsulated in the creation, Susan admitted she was thrilled with the outcome.
She said: "What can you say? They have done a very good job. It feels fantastic. It was such a great process to be involved in and it looks very realistic. She`s doing a better job than me!"
While the wax model - wearing a sophisticated black outfit donated by the singer herself - will go on display alongside the likes of British TV veteran Bruce Forsyth in the Big Night In section of the attraction, Susan admitted she would rather her likeness was stood next to music mogul Simon Cowell.
When asked where she would like her waxy alter-ego to be placed, she said: "Next to Simon Cowell, of course, no doubt about that!"
Matthew Titherington, general manager of the attraction, added: "We are delighted to welcome Susan at Madame Tussauds Blackpool as we put finishing touches to our exciting new attraction."
Justin Bieber, Lady Gaga and Taylor Swift are among the other stars recently immortalised in wax by Madame Tussauds.
