Jenny McCarthy's Bob

A: Actually, Jenny McCarthy's sleek bob is intended to draw attention TO her jaw line, rather than de-emphasize it.
As you can see in other photos of Ms. McCarthy, she has a naturally broad forehead, with rounded cheeks and wide eyes and her lower face tapers to a sharper chin. This creates an inverted triangle effect which the new bob cut balances by creating a "point up triangle" effect using the lines of the cut/style.
To soften a strong jaw line, you want to use a hairstyle that doesn't draw focus to the area. A neck-length to shoulder-length cut with razored ends and some layering to create a soft look that has extra volume in the upper portions would be good to balance a strong jaw, provided there are not other factors that would preclude this style from suitability.
