Sydnie Christmas gave fans a night to remember at ExCeL London with a show-stopping live performance of “She Used to Be Mine”, the angsty ballad from the Broadway hit Waitress—and her powerful rendition had fans reaching for tissues and showering praise online.
The rising star, who’s quickly becoming one of the most talked-about vocalists in the UK, took the stage during Musical Con 2024 and delivered a pitch-perfect, emotionally charged version of the beloved song. Turning the haunting ballad into her own moment of triumph, Sydnie left the audience in awe—and many in tears.

Fans wasted no time sharing their reactions online. “Wow, such emotion and storytelling when she sings. A true generational talent and sincere soul,” one admirer wrote.
Another gushed, “How can Sydnie sound so brilliant? Never have I heard such a perfect singer. She gives me shivers up and down my spine every time I hear her sing.”
Her performance sparked even more excitement as fans recalled her sold-out show in New York’s Sony Hall earlier this year. “Phenomenal, once-in-a-lifetime talent! Conveys such emotions that I constantly find myself wiping away tears. Thank you, Sydnie, for sharing your beautiful voice. Can’t wait to see you in London!!” one comment read.
Even those who watched the performance after the fact were moved: “I had to watch this with the sound off, and I still got the sniffles. When I can cope, I’ll go full screen and full volume. Don’t know how I’m going to manage next month when she sings this live on tour!! ”
Some fans are already imagining what’s next for the powerhouse vocalist. “Her interpretation of the song is perfect. Perhaps she could be in the musical someday?”
And many couldn’t help but draw comparisons to the greats: “Isn’t she at or above the level of the divas of all time? This was great for what appears to be an audience member recording”
With every note and every pause, Sydnie Christmas continues to prove she’s more than a singer—she’s a storyteller. One fan may have said it best:
“Sydnie’s performances are always pure magic.”
