Katherine Heigl was spotted out on the beaches of Miami late last week, and the blonde beauty was out soaking up some more sun over the weekend.

It doesn't look like Heigl is taking vacation as a reason to throw caution to the wind either. She is holding an electronic cigarette in this photo, which the 'Knocked Up' actress has been using to help her kick the habit of real cigarettes.

Going right along with the healthy theme of her vacation, you can see photos below of Heigl eating a salad poolside, getting tips on how to simplify her life and, of course, showing off her bikini bod while splashing around in the water.
