Or is it all done on votes??

they'll decide when they know who has the lowest votes :/

Who knows?

It is made up as they go along to get the result then want.

What a fix they should have announced last night what the rules for tonight were but thet of coure would limit their option to get the result they want.

Usually the sing-off is abandoned at this stage and it's all down to the public vote, but this year they seem to be making it up as they go along, so who knows?

If Cher gets lowest votes, they will go for Judges choice otherwise straight elimination.

I agree with the poster above, if Cher is at the bottom, then there will be a sing off.
