North East singing hopeful Sam Lavery hopes her choice of song will be a lucky omen as The X Factor went all disco.
The 17-year-old from Coxhoe, Durham, is through to the last seven of the ITV talent contest, and is already guaranteed a place on next year's live tour.
Last night the remaining contestants had to perform a disco classic, and Sam chose Gloria Gaynor's I Will Survive.
Afterwards she Tweeted: "I loved every second of that!! Thank you so much for everything and for the continuous support!
The X Factor continues tonight at 8pm, when there will be no more life line vote, and the bottom two contestants will go into a sing-off, with one of them voted out of the competition.
