Katherine Heigl is still puffing on her electronic cigarette nine months after switching from real ones

Did somebody sleep through their alarm?

Katherine Heigl was caught in public in white pyjamas that featured her monogram on the pocket.

The 32-year-old actress hid behind a pair of sunglasses and was carrying a steaming cup of coffee as she made a dash from her car.

She teamed her look with a beige leather bag and flip flops as she arrived at her mother's Los Feliz home in California.

The Knocked Up star is clearly not a morning person.

One notable missing accessory was her 'smokestik' electric cigarette.

The Hollywood star, who has a two-year-old adopted daughter Naleigh with husband Josh Kelley, is often spotted with the contraption in hand.

In fact, she was seen smoking it earlier this week in upmarket Japanese restaurant Matsuhisa.

Katherine has been using the device for the past nine months after giving up smoking.

She discussed the quit smoking aid during an appearance on David Letterman in September, when she showed the late night host how to smoke her customised 'bejewelled' version.

Describing her efforts to give up the unhealthy habit, Katherine said: 'You start once a week, maybe with a cocktail with friends at a bar, and then you buy your first pack during a really stressful break-up, and then it's downhill from there.'

'I've tried everything. I've tried the patch, I've tried the gum, I've done Chantix, twice, which made me bananas (a prescription medicine used as a quit smoking aid).'

The electronic cigarette uses water vapour and liquid nicotine. It is legal to use inside as the water vapour breathed out by users is harmless to others.

As far back as 2008, Katherine was publicly discussing her battle with quitting after attracting negative press when she was constantly pictured smoking.

Katherine is back in Los Angeles after filming her part in the ensemble comedy New Year's Eve in New York last month.

The actress stepped in at the last minute to replace Halle Berry after she pulled out to concentrate on her custody battle with Gabriel Aubry.

However, the issues were resolved and Halle was able to take part in the film after all, in a different role.

The rom-com, directed by Garry Marshall, stars a host of big names, including Sarah Jessica Parker, Jessica Biel, Robert De Niro, Ashton Kutcher, Lea Michele and Zac Efron.

Hilary Swank, Michelle Pfeiffer, John Stamos, Sofia Vergara and Abigail Breslin also appear in the movie, slated for release in December.
