Petra Ecclestone and her husband James Stunt have been targeted in a 'jealousy-fuelled' petrol bomb attack.
The F1 heiress and her husband are believed to be 'really alarmed' after the firebomb landed next to Petra's Range Rover.
The couple, who have three young children, were fortunately not home during the attack on April 24.
However two men are understood to have been spotted on CCTV running from the £68m home in west London.
A spokesperson from the Met Police confirmed police were called at approximately 5.25pm on Sunday 24 April to reports of a fire outside a residential property.
"Officers and the London Fire Brigade (LFB) attended the scene. The fire was dealt with by London Fire Brigade," a spokesperson confirmed.
"No reports of anyone injured. Detectives from Kensington and Chelsea are investigating. No arrests and enquiries into the circumstances continue."
A spokesman for the couple said the attack is: "Thought to be the action of a disaffected member of the public who disapproves of the Stunts' lifestyle."
Meanwhile a friend reportedly told Mail Online: "The whole family are really alarmed by this.
"It's horrific. They are determined to find out who was behind the attack."
Socialite, model and fashion designer Petra is the daughter of F1 boss Bernie Ecclestone and Armani model Slavica Ecclestone.
She married husband James in Rome in 2011 wearing an £80,000 Vera Wang dress - the wedding reportedly cost £12m.
The couple have three children - three-year-old daughter Lavinia and 11-month old twin sons James Robert Fredrick Jr and Andrew Kulbir.
