Yes.

Watch Our Best Bloopers Segment 20 minutes into the program where she's outdoors with the mosquitos; she's hanging out of a jeep or car with a pair of binoculars.She's wearing a denim jacket and the Camels are in the upper left pocket (on the right side when you're watching). You can only see the upper portion of a Camel cigarette pack.

And, all the people who get make overs on her show always comment afterwards how much Stacey smokes.

She smokes about two packs a day, but doesn't really consider it two packs since she never really finishes a whole cigarette. Stacey is one of those smokers who lights up a cigarette, and then throws it away after a couple of puffs. The most she'll smoke is about half a cigarette.
Although, after she broke up with her fiance, she started smoking even more heavily to help calm her nerves. The irony is that smoking was what first attracted her fiancee to her because it gave her this sexy allure.

She had smoked before, but she really picked up the habit when she first started working in the fashion industry. Most of the people in that industry smoke and so she started smoking more to fit in. A cigarette is almost considered an accesorry in that field especially when everybody goes out to the bars to drink.

Of course, she's not ignorant of the health risks. And, she's tried to quit before, unsuccesfully. She found that the cigarettes had helped speed up her metabolism and kept her thin. When she tried to quit, she discovered to her horror that her weight balloned up to almost 10 pounds. Of course, this meant she'd have to throw away all her clothes. And, this threatened her career in front of the cameras.
