Janet Devlin revealed she and rival X Factor contestants Misha B and Amelia Lily were treated by former Destiny's Child star Kelly Rowland to help them relax before the next live show on Saturday.
The 17-year-old from County Tyrone said: "Kelly's given us a lot of support. We've all been really stressed, all the girls have been really stressed so we got to go to a spa, that was lovely.
Janet hopes to stay in touch with the X Factor judge after the show is over.
She said: "I'm not going to lose touch with her. She looks after us so well that you can't break that bond that you've made throughout the show."
And she insisted she won't be disappointed if she doesn't win.
"Not everything is about winning anyway. What you've got to do is do your best and hope it's good enough."
