Mischa Barton steps out for lunch with boyfriend Gian Marco Flamini after casting her ballot to vote

She stepped into the world of reality television with a starring role on The Hills: New Beginnings.

And Mischa Barton was in the mood for a casual day out as she went to lunch with boyfriend Gian Marco Flamini in Los Angeles on Wednesday.

The 34-year-old actress looked chic in an all-black ensemble after boasting about turning in her ballot and voting early in the upcoming presidential election.

Mischa rocked a black T-shirt with matching denim slacks which were hemmed above her ankles to reveal a pair of brown leather boots.

She added a comfortable jean jacket and black velour purse to her casual ensemble, and made sure to protect herself and others amid the ongoing coronavirus pandemic by wearing a blue face mask.

Gian rocked an equally cozy denim ensemble with light wash jeans and a sweater worn underneath a lightweight jacket.

The Love Unplugged star was first spotted with Gian, who is also an actor, earlier this year, and they appear to have quickly become inseparable. 

Earlier in the day, The O.C. star shared her excitement as she flashed her ballot on Instagram before heading to one of the many official drop boxes around Los Angeles County.

‘As you can see I’m pretty excited to be heading to the Ballot Box,’ she wrote. ‘Please get out there and vote – I still hear so many people are thinking of not voting and that breaks my heart! Whyyy?!?!

‘Vote for what you want to see! Do your research and be proud to participate, I know I am!!!!!’

Mischa’s most recent big screen role was in the dark comedy Spree as a passenger for a ride share driver, who was played by Stranger Things star Joe Keery.

The movie, originally shown at Sundance, was released on video on demand last month also features Franke Grande, Lala Kent and David Arquette.

Despite making her reality television debut just one year before, Mischa confirmed she wouldn’t be returning to The Hills as it begins filming its second season.
