Courteney Cox stars on "Cougar Town," and she has a little advice about romancing younger guys.

"Don't worry about what people say," Cox, 45 -- who is married to David Arquette, seven years her junior -- told "Extra" between filming scenes for her ABC hit.

"Just go out and have fun," continued Cox. "And don't worry about them leaving you later!"
