Petra Ecclestone and Sam Palmer enjoy a family day out at Disneyland with their ...

Petra Ecclestone was every inch the doting mother as she enjoyed a family day out to Disneyland with her four children on Friday. 

The 32-year-old heiress sweetly carried her 18-month-old daughter, whose name she has not yet revealed, on her hip as the family excitedly ran around the theme park. 

Meanwhile, her other three children, Lavinia, eight, and twin boys James Robert Fredrick Jr and Andrew Kulbir, both six, followed dutifully behind.  

Petra cut a casual figure in a pair of forest green leggings and a cropped grey T-shirt as she kept an eye on her kids as they traipsed around Disneyland. 

She completed the laidback look with an enviable black Prada crossbody bag, white tube socks and a pair of multicoloured trainers. 

The heiress and her beau looked to be having a blast on the Matterhorn ride as they flew around corners while clutching the safety bar in front of them. 

They also spent time in the Star Wars Galaxy section of the theme park and tried out the new Rise Of The Resistance ride.  

The group seemed to be having a fantastic time at the happiest place on Earth as they chatted and laughed while walking between attractions. 

Sam melted hearts as he carried his cradled his young daughter in his arms while she nestled into his chest. 

The daddy-daughter-duo sported matching white T-shirts for the family day out with Sam keeping things covid-safe in a mauve protective face mask.  

Petra welcomed her youngest child with Sam in April last year, while she shares Lavinia, James, and Andrew with her ex-husband James Stunt. 

Petra and James' divorce was finalised in October 2017, after six years of marriage. While no details of the settlement were released, it was reported that James signed a £16million prenuptial agreement, with Petra also awarded sole custody of the couple's three children.  

The stateside visit comes after Petra and Sam recently put their £170 million home in the UK up for sale.   

In a recent clip, produced by Architectural Digest, Petra and Sam introduce people to their Grade II listed home, which has been transformed into a modern palace plush with gold and crystal detail. 

As cameras are let into the home for the first time, Bernie Ecclestone's youngest daughter, who's family is worth an estimated £2billion, says: 'This project took me five years to complete and is a home that I absolutely adore.'

It's an unusual step for fiercely private Petra - who admitted the home will be 'hard to sell' and has  previously spoke about how she relocated her family to Los Angeles as she no longer felt safe at her luxury London home.

Walking into the home, Petra explains: 'We custom built this gold bar, obviously it's to entertain and to have lots of parties that we do not have. 

'I love this chandelier, it's a custom chandelier with 150,000 pieces of crystals, going from bronze finishes to gold which is obviously my favourite colour. 

'This couch is obviously one of my favourite pieces of the house, and the panther is my favourite animal which shows inspiration throughout the whole house. 

'This is one of my favourite rooms of the whole house,' Sam adds.

'So the first thing that hits you when you enter this room is this magnificent crystal chandelier which is 150,000 Swarovski crystals. 

'Behind us you will see we have a fabulous bar which is all custom built, And obviously, the panther, which features throughout the house is seen in here as well. There's
