...Mairead Nesbitt is Tinkerbell my goodness is she Tinkerbell lol...
She's the fiddler in the Disney Tinkerbell DVDs, and Meav sings "Where the Sunbeams Play" in "Tinker Bell and the Lost Treasure."
But, petite as she is, Mairead is too big for a pixie. An Elf, maybe, using a glamour to pass for merely human. She certainly seems to be partly immune to gravity. But maybe, like gymnasts and ballerinas, she's just a lot stronger than she looks.
