Hilary Duff CigaretteUh oh. There are a lot of celebrities who like to puff away on a cigarette every once in a while, but new mom Hilary Duff wasn’t thought to be among them.

Yes, the former Disney starlet was photographed holding a lit cigarette outside Rock & Reilly’s Irish Pub in Los Angeles on Friday.

The internet was taken aback at the sight of a new mom lighting up, although it certainly wouldn’t be the worst thing Hilary has ever put in her mouth.

Duff gave birth to baby boy Luca in March and has reportedly been slaving away at the gym to lose some weight.  Let’s hope she hasn’t resorted to nicotine too.

The actress immediately took to Twitter to try and explain away the photo with a slightly less-than-plausible explanation…

Yikes me holding a cigarette for my friend might have been a bad idea! pretty bummed about the photo.. Sorry guys, looks worst than it is!

Holding it for a friend?

Yikes, did her dog eat her homework too?

Let’s hope she’s keeping that second hand smoke away from the baby.
