Will there be a sing off between the bottom two this week, as the judges no longer have the power to vote?

Can't remember what has happened in the past....

Act with the fewest votes goes I believe

There's no sing off from now on.

Act with the least amount of votes is gone from now on.

The act with the fewest votes goes. No sing-off. Could be any of them. I'm not sure any of them can be classed as 'safe'.
