London, September 5 : Actress Katherine Heigl has reportedly managed to quit smoking.

The Knocked Up star, who wanted to quit the ill habit for quite some time now, has apparently not taken a puff for a month, which has boosted her health.

"She feels so much better," the Daily Express quoted a source as telling Us Weekly magazine.

Heigl had previously said: "I started smoking when I was 24, because I''m an idiot.

“I don''t enjoy it so much now, because I''ve become such a slave to it. I hate planning my life around when I''m getting a cigarette."

She had decided to quit tobacco in July. (ANI)
