Petra Ecclestone is effortlessly chic in a leather camel coat as she enjoys a dinner with Sam Palmer

Petra Ecclestone showed off her style credentials on Friday as she stepped out for a romantic date night with her fiancé Sam Palmer in Santa Monica.

The Formula 1 heiress, 33, oozed sophistication in a long leather camel coat, which she wore over a tight brown top.

The couple, who welcomed Minnie in April last year, enjoyed time off parenting duties and appeared in high spirits as he left the restaurant.   

Petra complemented the look with casual blue jeans and opted for comfort with navy blue trainers.

Her blonde locks were styled straight and she wore a brown handbag slung across her chest.

She completed her look with several gold necklaces, with one saying the word ‘Mumma’ across it.

Sam looked handsome in a bright blue jumper under a black jacket and teamed with dark jeans. 

Petra is also proud mum to nine-year-old Lavinia, and twins James and Andrew, six, whom she shares with ex-husband James Stunt. 

Petra has been incredibly health conscious ever since she developed viral meningitis, was hospitalised for a week and left bedbound for a month back in September 2005, aged just 14.

Meningitis is an infection of the meninges, the protective membranes that surround the brain and spinal cord. It can be caused by bacteria or a virus. The meninges can become inflamed, and if it is not treated it can lead to permanent brain and nerve damage.

Petra previously told MailOnline her immune system struggled as a result of fighting off the illness and made her turn to vitamins and acupuncture.

She said: ‘I also suddenly started to catch every bug going. I tried to fight back with high-strength multi-vitamins and extra Vitamin C and zinc for an immunity boost but it was acupuncture that made the real difference in getting me on my toes again.’ 

Speaking about her experience, Petra said: ‘Before getting meningitis, I was such a hypochondriac, worrying about the slightest ache.

‘Ironically, I overlooked meningitis because the symptoms seemed like flu. I guess you don’t realise how healthy you are until it is taken away from you.’
