The gorgeous opera singer told us she is planning on performing an iconic Opera track for the final live show... but with a twist.
Lucy revealed exclusively to us that everyone will know the track and associate it with Opera, but the song is usually performed by a a man.
The 26-year-old wowed the judges with her voice at her first audition and last week topped the pubic vote in her semi-final to make it into the weekend's final.
And along the way she's picked up quite the fanbase... and plenty of male admirers.
She told us: "I've had male attention... someone actually sent me a picture of him with no top on and a rose in his mouth saying 'Good luck for tonight' and I was just like... 'Thanks... '"
But what does her boyfriend make of it all? Lucy says: "I don't think he knows! Well, he does now!"
The BGT final airs on Saturday night on ITV where Lucy will be competing against the likes of Bars and Melody, Collabro and Darcy Oake.
