Tamara opted for an uncharacteristically pared-down look, rocking a simple nude sweater teamed with black skinny jeans.

Shielding her eyes behind square-frame shades, the mum-of-one appeared to go make-up free during the relaxed outing.

Sophia, meanwhile, looked typically stylish in a festive red jumper and fur-trim high trainers as she kicked back in her pink buggy.

Petra echoed Tamara's casual vibe, opting for a chic pair of red sports-luxe joggers teamed with a white slogan T-shirt   

The family was followed closely by a pair of security guards during the festive shopping trip.

Tamara's outing comes after she decked out her £75million Kensington mansion with a real-life sleigh and lavish decorations in the run-up to the festive period.

And she was equally meticulous about creating the 'perfect' Christmas tree, threatening to stab husband Jay Rutland with an icicle after he complained that she was like an 'army general'. 

Tamara left viewers shocked as she showed off her 'mad' side while decorating the Christmas tree, in scenes from her ITVBe reality show Tamara's World on Wednesday.

After buying a plethora of personalised baubles, stars and other festive knick-knacks, she confessed guiltily to the camera: 'Jay thinks I'm a little bid mad, but secretly he loves it.'

Jay deadpanned: 'It sounds like another low-key production!' as Tamara beamed: 'I think I've really outdone myself.'

Discussing the tree's decoration, she admitted: 'Yes I have OCD and in an ideal world I would like there to be no naked patches. But it's all about the taking part.'

Despite her insistence that it was about making memories, the socialite was soon taking charge - instructing Jay and Sophia on where to place the baubles and spraying the tree with 'unicorn scent'. 

Rolling his eyes, Jay said to the camera: 'Tamara is an absolute nightmare. 

'She can't just let you get on with it - she has to oversee it like some army general. Tamara, zip it up and let me do the tree!'

Working his way around the fir tree, he told her: 'Tamara just relax your pants.'

Baring her teeth in irritation, she replied: 'I would like to stab you with that icicle.'

In his eagerness to hang a particular bauble off a branch, Jay then teetered and lost his balance - almost crashing into the tree and ruining everything.

Open-mouthed with shock, Tamara squealed: 'You could have fallen and impaled yourself on an ice dagger!' 

Later in the show, Tamara broke down crying as she and Jay discussed plans to have a second child.

Sobbing, she admitted: 'I'm scared I wont love anyone like I love Fifi,' but Jay hugged her and reassured: 'You will. I know you will.'
