Writes a spy:

Today at the final dress, it was pretty obvious why Reneeeeee would cancel her Normas – the “Sempre libera” was SCARY bad – completely off the voice for the mewing and really sloppy coloratura, and then she had to go back on-voice to try and get to the Bb/B/C/Db area. The repeated C’s were especially hair-raising, and she didn’t actually get up to the pitch on any of them in the whole aria. A friend [also] watching the dress said it was uncomfortable and worrisome to have to listen to her try and get through it. While she can still produce creamy sounds in her basic rep, her ability to sing fioritura (which, while totally wrong for bel canto, was impressive at one time) is basically gone.
