Both glamorously turned out for the London bash - n aid of Silent No More Gynaecological Cancer Fund and Cancer Research UK - the sisters saw the humour in their props, but pouted into the camera for the full effect.

Tamara - the eldest of the two sisters - took the chair, crossing her legs elegantly in a shimmering black dress with a thigh-high split.

It was a rare night out for the mum-of-one, who recently admitted that she finds it hard to leave her three-year-old daughter Sophia at home.

As always, the beautiful elder daughter of Bernie - who lives in London with her businessman husband Jay Rutland - was well-coiffed with her hair flowing in long waves around her shoulders and her make-up polished to perfection.

Younger sister Petra showed off her lithe figure in a plunging minidress, similarly picking out festive sparkle in the spirit of the season.

She offset the glittery number with a pair of fluffy heels, ultimately towering over her big sister.

Finding support from her sister and best friend, Petra is overcoming her £5.5billion divorce from businessman James Stunt at present.?

The model has only been seen in public a couple of times since her divorce from businessman Stunt was finalised in a five-minute court hearing last month.

The couple, who have three children together,?had been back and forth to court this year as they geared up for a bitter fight over their estimated £5.5billion fortune.

But when their heavyweight legal teams came before a judge it emerged the warring pair agreed what will be one of Britain's biggest ever divorce settlements.

Now a single mother, Petra recently spoke out about how growing up with money has affected her life.?

'I think people want to be able to hate me. I think that because my father is wealthy and now I am living off his money, they hate it,' Petra told The Telegraph in July.

She added: 'I feel that wealth is almost harder than fame. When you are wealthy, people use you and they want money out of you.?

'There is always some sort of ulterior motive. Whereas if you are famous, people are not going to become famous by being your friend.?I just feel people become so greedy around wealth. It changes people.'

In 2012, the man behind the money hinted that he was worried about his daughters blowing their fortune on their wardrobes.

He told The Independent at the time: 'I don't think they should have bought handbags and shoes but anyway, they are in the fortunate position of being able to.'

Tamara, who currently stars in her own new reality show Tamara's World, lays claims to a £5million wardrobe.?

Commenting on Tamara and Petra's London properties - which were valued at £45m and £56m respectively at the time, he added: 'Actually, all the properties that my daughters have bought they could sell today for big profits so any handbags and shoes they have bought fall into insignificance.'?

The duo are now full-time mothers, with Tamara publicising her inseparable relationship with her daughter Sophia but Petra choosing to keep her children's lives more private.?

In September, the model spoke to Vanity Fair about her hopes that women could be more open about their vaginas.

She said: 'I remember at school talking with some friends, and saying we had 'two holes', and we got in trouble with the teachers.

'So it was kind of ingrained in us that it was a private thing. And, in the classic British way of 'keep calm and carry on,' we never discussed things like Pap smears and other important issues that need to be discussed.'

Suki concluded: 'Half the population has a vagina and a period and it's still something that seems to be 'embarrassing' to talk about.'
