Every week Lily Collins is seen with a smoothie from Earth Bar in her hand, and it seems the eco-friendly cafe is rubbing off on her wardrobe.

Because on Wednesday, the actress picked up a healthy drink wearing an outfit perfect for any budding hippie.

Wearing an oversized knitted jumper with a paisley maxi skirt and sandals, it looked like Lily's next stop was to find a tree to hug.

She had enjoyed a few days in Paris for the biannual fashion week but on Monday she was in Los Angeles looking every bit the California Girl. 

The 25-year-old actress appeared happy and relaxed as she stopped by her mother's antique shop in Beverly Hills for a catch-up after returning home from the French capital over the weekend. 

Displaying her immaculate sense of style, the Love, Rosie star looked effortlessly chic in an unusual denim biker gilet, which she wore layered over a simple white tee.

The British-born beauty kept the rest of her look casual, opting for a pair of black capri pants and ditching her heels in favour of a pair of leopard print pumps. 

Lily wore her newly-cropped brunette locks pinned back from her face in a cute up-do, and opted for minimal make-up to showcase her naturally flawless English rose complexion and porcelain skin. 

The daughter of British rock legend Phil Collins sheltered her eyes from the Californian sun with a pair of dark shades, and toted her belongings in a cute tan leather shoulder bag as she meandered down the street. 

Lily touched down at LAX on Saturday evening, ditching the fuss and feathers of Fashion Week in favour of a flowing grey sweater and casual black trousers.   

The screen star strode along in white sneakers and threw a black and white scarf around her neck.

She appeared to be make-up free and concealed her eyes behind dark oversized shades, while showing off the new pixie hair-cut she debuted in February.

Lily was accompanied by a couple airport assistants, one of whom pushed her cart of luggage.

The brunette beauty went for comfort that day, though her style is evolving to become 'edgier and sexier,' she told Lucky magazine last year.   

It seems Lily had quite the cultural experience in the City of Light, documenting some of the unique artefacts, designs, and street art on her Instagram account.

The daughter of Phil Collins even met up with Chanel creative director Karl Lagerfeld, with whom she posed for a friendly photo.

Lily captioned it: ‘Enough said. Thank you @karllagerfeld. Words can't express my gratitude and honor #LilylovesLagerfeld...’

She was likely feeling quite star-struck during the trip, having previously confessed to feeling in awe when she receives invitations to prestigious awards ceremonies and high-profile events.

'I still feel like a little girl dressing up and getting to go to a pretty party', Lily told Lucky magazine. 

The star has no reason to feel out of place among her showbiz peers thanks to her experience growing up with such a famous father.

She added: 'Growing up, it wasn't impossible that, say, Elton John might pop over for tea.'

Meanwhile, Lily is counting down the days to her 26th birthday on March 18th.

The last week of February, she Instagrammed a photo with a friend, writing: ‘Kicking off birthday month with @arvandy. "March"ing into 26, diving head first, best foot forward...’

And Lily is kicking off her 26th year right, with the release of a new Untitled Warren Beatty Project on May 21.

She plays a 1950s Hollywood actress called Marla Mabrey who engages in an affair with ageing billionaire Howard Hughes (Beatty).

Taissa Farmiga (American Horror Story) Chace Crawford (Gossip Girl), Alec Baldwin, Matthew Broderick and Candice Bergen also star. 

Lily is loving what she does for a living.

'One day I would love to be a mom, but right now I’m so excited about my work,' she told Lucky. 'I like disappearing for a little while. 

'I always wanted to be someone who could take other people into a world with me. As an actor, I’m able to jump into a story and become someone else for a time. It’s a beautiful journey.'
