Sydnie Christmas

Christmas was born in Gravesend in Kent and studied at the D&B Academy of Performing Arts. After graduating in 2014, she went on to make her stage debut in the Kings Cross Theatre production of the jukebox musical Lazarus. She later went on to perform on cruise ships including Independence of the Seas and Quantum of the Seas where she appeared in productions including Grease and Starlight Express.

From 2020 to spring 2023 she was at Starlight Express in Bochum, Germany, first as ″swing″ (responsible for understudying multiple ensemble tracks and being able to replace several cast members), later playing Carrie the Luggage Car. She also appeared in Stage School and took a zero-hour contract at a local gym.

After finding that her career was struggling, she auditioned for the seventeenth series of Britain's Got Talent. At her audition, which was broadcast in 2024, she sang "Tomorrow" from the musical Annie after which she received the Golden Buzzer from Amanda Holden and advanced straight to the semi-finals. Christmas sang Paul Anka's "My Way" in the third semi-final, which she won with 37.9% of the public vote. She was the bookies' clear favourite in the final, despite "fix claims" regarding her previous professional experience. She closed the show, singing "Somewhere Over the Rainbow" from The Wizard of Oz, and was subsequently declared the winner with 27.2% of the vote.
