Julia Garner looks effortlessly chic in a casual look as she heads for lunch with Rob Lowe's son John

Julia Garner looked effortlessly chic as she headed out for lunch in Los Angeles on Wednesday with her boyfriend John Lowe. 

The actress, 30, who is set to star as Madonna in her upcoming biopic, wore a striped boat neck top which she tucked into a pair of high waisted jeans. 

She shield her face with a denim baseball cap and cat-eye sunglasses and teamed her casual outfit with a large black handbag. 

John, 29, who is the son of actor Rob Lowe and make-up artist Sheryl Berkoff, looked equally as stylish. 

He opted for a white vest, with a navy blue Ralph Lauren jacket layered over the top and beige trousers. 

The actor topped off his ensemble with a backwards baseball cap and a pair of white leather trainers.  

Julia's outing comes after Madonna, 66, revealed the 'struggle' behind resuscitating her 'scrapped' self-directed biopic, Who's That Girl.

'After struggling for days in LA, listening to producers and agents tell me why I couldn't make my film [I've] been working on...for four years,' the Queen of Pop lamented. 

'"Downsize! Down scale! Think smaller," they say. I realised that everything in my life is going to be challenged. No easy rides for me. I guess I should be grateful. It forces me to think outside the box. I did not have a normal life. I cannot make this in the normal way.'

Madonna then reached out to her social media followers for advice on whether she should make 'the story of my life' into a TV series or a feature film.

That same day, a source told DailyMail.com that producers 'laughed' at the singer's 'ludicrous' demand for a $100M budget.

Madonna co-wrote the script formerly titled Little Sparrow with Oscar-winning screenwriter Diablo Cody, who was later replaced by Independent Spirit Award-winning screenwriter Erin Cressida Wilson (The Girl on the Train, Secretary).

The superstar famously cast Julia as herself in June 2022 after a grueling 11-hour audition process and when Universal Pictures passed in January 2023, she told ET she was still holding out hope: 'Fingers crossed!'

The actress hasn't been pictured with Madonna since May 2023 when they attended the 58th birthday of famed lensman Steven Klein in Manhattan.

And now that the twice-divorced mother-of-six concluded her $225.3M-grossing, 81-date Celebration Tour on May 4, she is putting much of her energy back into the biopic.

The only other person Madonna was publicly considering for Who's That Girl was Uncut Gems alum Julia Fox in the role of her longtime gal pal, Debi Mazar.

The Material Girl previously helmed two dismally-reviewed box office bombs - Filth and Wisdom in 2008, and W.E. in 2011.

In July, Julia wrapped a mystery role in Zach Cregger's 2026 Florida-set horror film Weapons alongside Josh Brolin, Alden Ehrenreich, and Benedict Wong. 

But audiences can next catch her as wife and mother Charlotte in Leigh Whannell's horror film Wolf Man, which hits US/UK theatres January 17.
