Mary-Kate thinks back on her most embarassing moment 'We did a live fashion show, and when i was walking up the stairs, I tripped and fell in front of everyone!'

Ashley thinks back on her most embarassing moment 'When I was 8 years old we were on the Nickelodean Kids choice awards. I completely messed up my lines, not once but twice! I went backstage and cried because I was so embarassed. I still get so nervous at any live event.'

Both girls were embarassed when doing their first onscreen kiss in Passport to Paris. They had to do it over and over to get it right, plus it was in front of the entire crew!
