Some of us find it hard to stay in a monogamous relationship with one mascara. One day we want natural and defined lashes and the next we crave drama!

To lighten our makeup bags, MAC Cosmetics is launching MAC Haute & Naughty Lash this fall.

It has a 2-in-1 dual wiper system so you only have to carry around one mascara tube, yet you can choose if you want defined lashes or major volume. What's cool is that you actually use the same brush for both looks! The brush will go through different filters depending on where you open it from to give you the look you want.

Haute & Naughty Lash will be available from July 2010 only at www.maccosmetics.com and at all MAC store locations starting September 16, 2010 for $21.50.
