A far cry from Mad Men! January Jones dresses down in striped shirt and baggy jeans while shopping with son Xander

By Helen Zhao

She plays the always perfectly put together Betty Draper Francis in the hit show Mad Men.

But January Jones clearly keeps it more casual in her day to day life, dressing down in an oversized striped T-shirt paired with baggy cuffed jeans in Calabasas, Los Angeles on Friday.

The 36-year-old actress stocked up on groceries from Whole Foods with her two-year-old son Xander, who sported a bright yellow shirt.

The Mad Men star wore her blonde hair swept back in low-maintenance ponytail and shielded her eyes with orange sunglasses.

She carried a chic beige and black purse and strode along in black sandals.

January has never revealed the identity of her son’s father.

'It's just not something the public needs to know,' the Emmy nominated star told Net-A-Porter's The Edit last May.

'I don't divulge my sexual preferences. There are parts of your life - no matter what your job - that should remain private.'

Revealing such information may not be good for her professional life, she told The New York Times last May.

'Jack Nicholson once told me: "You should never give your personal life away, otherwise people will pick you apart. They’ll never believe in your character."

'Women should have lots of secrets,' January added, tongue-in-cheek. 'It’s our right to have secrets. Otherwise, what would we write in our memoirs?'

Meanwhile, the blonde beauty’s hit show Mad Men finished airing the first half of its seventh season on May 25. The next seven episodes will air in the spring of 2015.

Next year, the mother-of-one can also be seen opposite Ethan Hawke and Zoe Kravitz in the thriller, Good Kill.

It follows a family man who wrestles with his conscience when he begins to feel uncomfortable about his job as a drone pilot.
