Proving pregnancy suits her, the former Grey's Anatomy star slipped into a pair of dark denims which clung to her never-ending legs.

Keeping to her laid back look, Katherine teamed her ensemble with a simple v necked white tee as she layered a chic denim shirt over to sport the ever fashionable Canadian tuxedo.

The statuesque beauty worked a pair of flat scalloped blue pewter ballet flats as she draped her croc skin handbag over her shoulder while carrying an eye-catching tan notebook.

Neatly blow-drying her chin-length bob, she covered her features with a pair of oversized shades as she accessorised her attire with a silver statement necklace.

The 27 Dresses star's casually clad appearance comes after she was spotted on location in LA dressed in character filming her eagerly anticipated TV show Doubt. 

Katherine has been hard at work on the set of CBS drama Doubt after the American TV network rescheduled its original 2015-16 release date to 2016-17 following a disappointing response to an initial pilot episode. 

CBS have since commissioned a new pilot after recasting its two central characters, with Katherine replacing KaDee Strickland as Ellis and Steven Pasquale stepping in as love interest William 'Billy' Conway, a role originally taken by Teddy Sears.

The forthcoming show will also be the first to feature a transgender series regular in Orange Is The New Black star Laverne Cox, who retains the role she initially played in its doomed first pilot. 

Katherine is expecting her first biological child, a boy, with husband Josh Kelley after previously adopting daughters Nancy Leigh 'Naleigh' Mi-Eun, seven, from South Korea in 2009 and four-year old Adalaide Marie Hope, from the US in 2012.

The star admitted recently she 'feels chubby' as she prepares for the birth of her son in January. 

'I feel great. I don’t feel pregnant, I just feel chubby and that’s hard as an actress in Hollywood,' she told News.com.au
