It's the Strictly Come Dancing 2012 final this weekend, but just how will it work?
This year there's four couples in the final, the most there's ever been, and it's led to some tweaks in the format.
There are two live shows on Saturday night, which means we'll know the winner straight away without having to wait until Sunday's pre-recorded show.
Or having to look on Twitter to see if anyone's spoiled it.
The first show kicks off on BBC One at 6:30PM and will see the final four - Kimberley Walsh, Denise Van Outen, Dani Harmer and Louis Smith - performing their show dance and the judges' choice routine.
The lines will open after all four couples have danced for the first time.
The judges will mark all the dances but these critiques won't effect the outcome, with the public votes alone deciding who will win and who will be eliminated.
At the start of the second show, BBC One at 8:50PM, the lines will be frozen. The act with the fewest votes at that point will be eliminated in fourth place.
The lines will then reopen as the remaining trio will then perform for one last time, reprising their personal favourite dance of the series.
After that - and a performance from Robbie Williams - the lines will close for good and the winner will be announced!
