The 25-year-old "Transformers" star said all leading ladies are threatened by the same sell-by date when it comes to their appeal, reported Showzbizspy.
"As a woman you are limited. You have so many years and you have an expiration date and once you are over 40 it becomes very difficult to work in the industry in the same way.
"I feel like a lot of actresses feel pressure to work as much as they can while they are still in their 20s and early 30s. I don't have that fear. I just feel like kids are so much more important than any movie. They are so much more important than that. I'm not worried," Fox said.
