Looking a dead ringer for her mum, Rumer showed off her long lean legs in fitted black leggings. 

Flaunting her slender midriff she teamed it with a tight vest, she added a touch of rock chic in loose biker boots.

And tying her raven hair into two plaits, she accessorised with aviator shades and a beanie hat- despite the Californian sunshine.

After stopping by a studio in Beverley Hills, she was later spotted shopping in the same outfit, adding a loose grey T-shirt over her ensemble.

Meanwhile sister Scout also perfected her fitness routine, and was spotted checking her phone as she attended a workout.

Like her sibling she showed off her long lean legs in Nike leggings.

Making the most of her toned body, she wore a black vest with a red border, carrying her workout bag with her.

Meanwhile Rumer has recently finished filming thriller What Lies Ahead, due for release in 2017.

Emma Dumont from NBC's Aquarius and Kelly Blatz from Glory Daze will star along side her in the Rob Gardner directed indie thriller.

It centers on a woman, played by Dumont, and her boyfriend’s sister, played by Willis, who embark on an unexpected road trip from Georgia to New York.

As they get to know one another, an unseen peril begins to emerge that threatens to grow stronger with each passing mile.
