Katherine Heigl can't seem to kick her smoking habit - despite claiming she was going to stop lighting up. 

After saying she will be making a serious effort to stamp out the habit, our spies spotted the actress puffing away on the cancer sticks out at lunch with her husband Josh Kelley.

The Grey’s Anatomy star admitted she wanted to stop smelling like an ashtray earlier this year and vowed to quit after seven years of inhaling.

“It’s so stupid, I have to quit the old fashioned way,” she told The Washington Post.

“I tried the patch [and] tried gum. I hate the gum. It burns my mouth.”

But it seems the old-fashioned way isn't working either if these latest pictures of Katherine getting her nicotine fix are anything to go by.

You've been caught out Miss Heigl!
