Stacey is starring as fairy Tinker Bell in the touring musical show and last night she wowed the audience at a VIP night in London.
The former X Factor finalist and her Peter Pan co-stars wowed the crowd at Wembley Area, which included several celebrity faces.
EastEnders' Rita Simons took her kids to see the show, along with comedian Rufus Hound and former Two Pints And A Packet Of Crisps star Will Mellor.
Stacey's costume is made up of lots of silver, net and sparkles and is topped off with a giant blonde hairpiece and a pair of green wings.
In a recent interview with Reveal, Stacey described her role of Tinker Bell as "every girl's dream".
She said: "I'm playing a part that is every girl's dream really. Peter Pan is such a lovely story, it really is the best Disney film isn't it?"
Laughing, Stacey added: "I don't want to grow up! No one does!"
Stacey's come a long way since The X Factor. Watch her first audition here:
