Miley Cyrus
Hey, at least it's not salvia.
Lindsay Lohan
Let's face it. Lighting up a little tobacco is the least of LiLo's problems.
Kristen Stewart
The multitalented star of the Twilight movie franchise huffs and puffs at the paparazzi Down Under.
Robert Pattinson
Aw, Pattz. Edward Cullen doesn't smoke, and he's perfect in every way. (Then again, the vampire doesn't breathe either. Hmmm.)
Taylor Momsen
They say cigarettes stunt your growth, but the 16-year-old actress, who already models herself after the Gashlycrumb Tinies, scoffs at such dire warnings.
Katherine Heigl
Nothing says hangover special like a Bloody Mary and a cigarette...but the new mother is trying to kick the habit. You go, girl.
Johnny Depp
Go ahead, just try to find a picture of the actor smiling with his mouth open. (He's a crafty one when it comes to concealing his nicotine-stained choppers.)
Rebecca Gayheart
The former Noxzema girl takes a big puff, despite the fact that she's expecting her first child with husband Eric Dane.
Sean Penn
The Oscar winner announced he would give up cigarettes after seeing his father die from lung cancer in 2001. But last year, as president of the Cannes Film Festival jury, the Hollywood rebel defied a French antismoking law by lighting up twice during a press conference. Go figure.
Gwyneth Paltrow
"I'm so pissed off [smoking] gives you cancer," the actress told Elle magazine. "But then, once you have children, if you've witnessed a death like I did with my father, you just can't. But I've decided that when I'm about 70 I'm going to start smoking again. Why not?" Oh, maybe because GOOP wouldn't approve?
Scarlett Johansson
This shapely actress uses the gym, and the old-school method, to maintain her slim figure.
Colin Farrell
Do you think the Irish rebel would lose his bad-boy status if he quit smoking?
Jon Gosselin & Hailey Glassman
Other couples toast with champagne.
Shia LaBeouf
Fired up to be working on the Transformers 2 set?
Shenae Grimes
Pointing out that one in five teenagers smokes, the 90210 star tells haters, "I'm sorry if you don't like it, but this is who I am."
Kate Winslet
The acclaimed actress gets a free pass when it comes to smoking: She's British!
Leonardo DiCaprio
Unlike his famed costar, the award-winning environmental activist's cigarette addiction is a tad disconcerting.
Eva Longoria Parker
Somehow we don't think Tony would approve of his wife's sneaky cigarette break.
Courtney Love
Court's cigs are as essential to her as, well, breathing. So few were surprised when the rebel rocker was temporarily banned from flying after she sneaked some puffs in an airport departure lounge last year.
Mickey Rourke
Is secondhand smoke any way to treat a man's best friend?
Amy Winehouse
The songbird's sophisticated style is nearly ruined by that declassé ciggy.
Lily Allen
You're using matches to light those candles, right?
Samantha Ronson & Lindsay Lohan
We can't expect LiLo to give up every addiction.
