It's The X Factor semi-final this weekend and here's what Grace Davies will be singing.
As things stand six acts remain in the competition but only four will make it through to next week's grand final.
Each of the remaining six contestants will have the chance to impress the viewers at home, potentially performing twice over the weekend.
In a first for this year, the contestants will all be singing together having performed in their categories up until now.
This evening, the six acts will all sing for the first time as they celebrate the best of British music with the theme ‘Cool Britannia’.
Grace will be covering Life On Mars by the late David Bowie.
"I’ve waited the entire series to perform this song," she tweeted ahead of tonight's show. "My favourite song to cover, ever. ♥️
"I hope I do you guys proud, and do the song justice. PLEASE remember to #VOTEGRACE 💋"
Grace and the other remaining contestants will be hoping everyone does vote as one act will be leaving at the end of Saturday's episode.
With the sing off gone, viewer votes alone will determine who loses their place in the competition.
The remaining five acts will then go forward to Sunday's show.
They'll all perform a brand new song in a bid to get through to next week's final before one more act is sent packing.
The X Factor 2017 continues this Saturday and Sunday night on ITV, starting at 7:30PM.
One act will be leaving at the end of each evening's show.
Guests over the weekend will be Ed Sheeran and James Arthur.
