Sorry guys been trying to find out why there's 17 but had no luck so far.. So if someone is kind enough to let me know that would be great!

Simon originally put through Simone, Tiah, Rachel and Drew. He sent Melanie home. After all the judges picked, Simon said he'd been on the phone to the others and they had made a mistake and should bring Melanie back. So he went to Melanie's house and brought her back making it a Top 17 !

In the girl's category there is an extra girl, totalling 5. All the other judges have four. Simon's show, Simon's rules (he is their mentor).

He felt he had made a mistake after rejecting a very talented girl (Melanie Amaro) at judges houses so invited her back and she is now on the show.

Each judge must eliminate one act from their category tonight (much like our week 1 format, but Simon has to get rid of 2 to make it even again)
