Inspired by a question from the "This or That?" thread that I didn't quite get, but I've been wondering this for a long time anyway:

Is Irina Grigorian, the "hula hoop girl" from Stars on Ice {???} the same "hula hoop girl" who appears on David Letterman with the "Grinder Girl" when he does "Will It Float?" on Friday nights? I've never actually seen Grigorian perform with an ice show, so have no idea if it's the same woman or not.
