cheap cigarettes onlineMexican actress Salma Hayek picked up smoking for a movie part and has been hooked for 10 years. But she says she’s finally kicked the habit.

The 45-year-old actress developed the bad habit when she played Mexican painter Frida Kahlo in a movie about her life.

Hayek confesses she got so used to puffing on cigarettes as the chain-smoking character, she couldn’t put them down when filming wrapped.

“I hated cigarettes and I had to learn how to do it for the movie…” she says.

“When I started, I was smoking some horrible, old Mexican cigarettes without a filter, because that’s what Frida used to smoke.

“So, at the beginning, I used to throw up after a couple of scenes and then I actually got addicted to that thing that I hated so much,” she said.

Her battle to quit has been an on-gain, off-again effort.

“I stopped (for) two years when I was pregnant and I was breastfeeding. Thank god I breastfed for so long because it kept me away from the cigarettes.

“I tried to give it up but then I picked it up again, I tried everything… [but] I am free and clear now. Yes! For good!” she proclaims.

Hayek’s career took off at 23 in 1989 when she landed the title role in “Teresa,” a successful Mexican telenovela that made her a star in Mexico.

Her American film career began with a starring role opposite Antonio Banderas in 1995′s Desperado, followed by a starring part opposite Matthew Perry in the 1997 romantic comedy “Fools Rush In.”

In 2007, Hayek confirmed her engagement to a French billionaire and PPR Chief Executive François-Henri Pinault.

She was pregnant at the time and gave birth to daughter Valentina Paloma Pinault on Sept. 21, 2007.

Hayek caused a stir when she was photographed smoking in Dec. 2008, while she was still breastfeeding.

She was photographed again, in Feb. 2009, breastfeeding a starving infant in Africa.

Salma said she was weening her daughter Valentina at the time and felt it necessary to feed the other child, too.
