Not me. Nikki's voice and mannerisms were fingernails down a blackboard to me. You either thought she was brilliant and hiliarious or you wanted someone to throw a green baize cloth over her for the duration. Casey's voice and manner sound pleasant and ordinary to me.
Not even remotely, but that's my opinion. Although I do know her from somewhere and she really reminds of someone but I can't think who and it's driving me craaaaaaaaaaaazy!
