The singer performed My Funny Valentine for the judges, getting them and the 3,000 strong audience on their feet.
Simon Cowell gushed: "This is what I have been waiting for. Your voice is liquid gold. You could sing the phone book.
“I want to remember the day I met Alice Fredenham because I think you’re so special.”
But it wasn't Alice's first shot in the reality telly fame game, having previously auditioned for The Voice.
None of the four coaches turned around for Alice and her cover of The Lady Is A Tramp, and she blamed the song choice.
"I sang another jazz number, The Lady Is A Tramp, and it perhaps was too up-tempo," Alice said. “I chose it with The Voice team, but yes, it was my choice and with hindsight, the wrong one because the chairs didn’t turn."
But Alice isn't bitter about the rejection.
She laughed: "It’s all worked out well in the end because I’m here and I’m so happy that I am!”
"They had their own reasons for not turning, I'm just really happy that the judges on Britain's Got Talent had the reaction they did, each to their own," she added to us this week.
