Twilight actresses Ashley Greeneand Nikki Reed are desperately trying to kick their nicotine habit with the help of fake cigarettes.

The two stars are conscious of their status as role models for their young fans and want to set an example by quitting smoking. And they’ve turned to imitation cigarettes SmokeStiks to aid them in their challenge.

A source tells Eonline.com, “Everyone on the cast (of Twilight and sequel New Moon) smokes, and they are all trying to quit because they are on Twilight and know they are in the public eye.

“(Greene and Reed) know they are role models for little kids. If there are a ton of paparazzi photos of them smoking, that’s not a positive image.

“SmokeStiks look like those fake cigarettes actors use in plays. There’s no smoke; it just lights up when you puff.”
