I doubt if there are many people who don't believe that the judges know the results of the phone voting. Her begging struck me as particularly desperate, so I'm wondering if she has serious concerns that her pets might end up in the bottom three and she'll have to choose between them.

Let's hope so

Only 2 of the remaining acts have been in the bottom 2 and they are both her acts. Of course she knows her acts are in danger!

Cos there is a higher risk of her acts being there as she has three left, like as said two of which have been bottom 2 before.
