Mad Men child star Kiernan Shipka fears she would struggle to cope with life in a regular school after spending most of her childhood receiving private tuition.

The 13-year-old actress has been playing Jon Hamm's onscreen daughter, Sally Draper, since 2007 and she has been home-schooled by tutors so she can fit her education around her job.

However, Shipka fears she would be unable to adapt if she ever had to go back to school.

She tells Britain's Es magazine, "Sometimes I think I'd like to go to regular school but, gosh, people my age are so dramatic - it's literally the most dramatic point, there's so much drama. Even with my friends. It's crazy to think that there's a whole school full of these people. That would be crazy. I couldn't handle it."

The teenager goes on to insist her co-stars help keep her grounded, adding, "There are no divas. We've been together seven years and we all get on. If I ever got brattish, everyone would be like, 'What are you doing?' and I'd feel terrible."
