It's no secret that movie stars make a boatload of money.

According to a new study, as actors age, the amount of money men make versus the amount of money women make differs greatly.

The study, from the Journal of Management Inquiry, shows that Hollywood starlets make the most at the age of 34- after that- the money tapers off.

This differs from the men. They keep earning their peak salaries until the ripe old age of 51.
