I once saw someone suggest Kelly Clarkson as Maureen and a part of me died inside.
Jessica Simpson would be awful as Maureen, she can't sing without her breathy voice, which compared to Idina at her worst makes Jessica sound like a emphezima patient; she can't act anything but dumb blonde and is too mainstream to make a believable lesbian performance artist.
Basically any mainstream pop artist that relies too much on the magic of studios to make them sound like good singers. Especially since the majority of them can barely sing, let alone act.
Like a firework unexploded
