Cameron Diaz Carries This $9 Beauty Item In her Purse

Cameron Diaz always nails the perfect California girl look-----blonde hair, blue eyes, warm, golden skin, with polished, NOT overdone makeup.

We were happy to find a little beauty nugget from the pretty 39-year-old actress.

Cameron Diaz tells InStyle magazine that this little number is always in her purse:

Revlon Just Bitten Lipstain by Colorstay in Passion ($9, at drugstores). We found a tube at Drugstore.com.

The Just Bitten lip line has been around a a few years now, and we can see why this is a Revlon keeper. It's a 2-in-1 product---lipstain and balm in a magic marker-type applicator.

Passion is practically a cult fave with its healthy pink, flush shade.

And it's quick and easy to use:

"Apply marker directly to clean, dry lips. After 30 seconds, apply the balm for moisturizing shine."

And the stain lasts for several hours...no kidding.

Great beauty tip for the budget-conscious, Cameron Diaz! Thanks.
