30 Rock creator Tina Fey has warned her daughters to stay clear of acting as a career.

The 43-year-old actress and writer has revealed that she will try to push her two girls, Alice, seven, and 22-month-old Penelope, to pursue a career behind the scenes as writers.

Speaking to HELLO! magazine, Fey said: ''I once showed Alice a clip from the Broadway production of The Little Mermaid. About five seconds in, she pointed to one of the actresses saying, 'I want to be her!'

''I was saying, 'Oh no honey, you don't want to be her, you want to be the person who writes the lines she says!'''

When asked what she tells her family about her professional life, Fey replied: ''That it's at least as interesting to be working behind the scenes as it is in front of them.''
