Emily Osment (she plays Lilly, on Hannah Montana) and Hailey Joel Osment

Spencer Graham (from Greek) and her dad (I forget the dad's real name..the guy from Frasier)

I was also shocked to find out that MK&A Olsen had other siblings! I dunno why but I guess I just found it weird because there was always SO much attention on the twins. I wonder how the other siblings felt when they were growing up and their twins sisters were always in the limelight
