No bwayondabrain, that's not true.
There's no way to know how they felt towards each other and, honestly, it really doesn't matter.
But if you want my opinion, I think they weren't the best of friends but had a professional relationship. As Kristin Chenoweth said on opening night at the press line, "Off stage we both have our own best friends and are our own people, but on stage, when we're together, we're TOGETHER."
Part of me wonders, though, why Chenoweth seems to be hostile towards "Wicked" these days. A couple months ago she said in that interview with a Christian magazine that it was "bad situation" backstage and that when she said she wasn't extending her contrasct they threatened to not campaign her for the Tony.. it was just so odd for her to come out of nowhere and see that.
But alas, we'll never know.
Tonya Pinkins: Then we had a "Lot's Wife" last June that was my personal favorite. I'm still trying to get them to let me sing it at some performance where we get to sing an excerpt that's gone.
Tony Kushner: You can sing it at my funeral.
