Actress Gwyneth Paltrow says she smokes one cigarette a week and added that she would never smoke in front of her children.

"I smoke one cigarette a week. The girlfriends I smoke with know about it, but I would never do it in front of my kids," a magazine quoted Paltrow as saying.

Paltrow, who has two children - Apple, 9, and Moses, 7, - also said that her kids are her "best achievement" and marrying their father, musician Chris Martin, was her "best decision to date", reported a website.

She said, "I was really lucky to have two healthy children, and I enjoy the process of raising them and watching these amazing human beings start to come out and be themselves."

She added, "My best Saturday morning would be, sleeping in and then having a really lazy day with the family, cooking, laughing and hanging out."
