Who is red headed girl in Zyrtec commercial?
Her name is Megan Paul.
Is the girl in the Toyota commercial with very short dark hair who says she isn't a celebrity the red headed daughter in Castle?
No. The red headed daughter on "Castle" is Molly Quinn. While they are both very cute, if you compare photos, you'll see Molly has bright blue eyes while the Toyota spokesperson has darker colored eyes. She actually looks just like the girl in the military recruitment ad....she has a mole on her face in that commercial. I think it's the same person.
