Kanye West helped decide what Kim Kardashian would wear for their Vogue shoot.
The 'Bound 2' hitmaker - who famously overhauled the reality TV star's wardrobe months after they started dating in 2012 - advised on his fiancee's make-up and outfits, but in an "encouraging", rather than critical way.
Make-up artist Aaron de Mey, who worked on the shoot, said: "He thought that her make-up looked very beautiful, but definitely had opinions on the dresses and the styles he liked best, but it was in a supportive way -- it was lovely to see them interact with each other."
Kim - who wore a series of bridal-style gowns in the shoot for the iconic publication - and Kanye were also photographed with their nine-month-old daughter North, and Aaron wanted the 'Keeping Up with the Kardashians' star to seem "realistic" in the family pictures, so kept her make-up fairly simple.
He explained to Cosmopolitan.com: "She was very open to something different, but Grace [Coddington] wanted to simplify her look because Kim is naturally gorgeous.
"Grace also had couture dresses made for her that were very sophisticated and ladylike, so we wanted to keep her look fresh and young -- almost like a twist on the style. Plus, she had the baby and Kanye with her in the pictures, so I wanted her to look realistic and not too untouchable."

Prince Harry's South Pole trek companions will compete in the London Marathon.
The injured servicemen and women who joined the 29-year-old royal in the charity walk on behalf of Walking with the Wounded have signed up to take part in the annual marathon next month.
All four of Harry's teammates are taking part, including Major Kate Philp, who lost her left leg in a bomb explosion in Afghanistan; Sergeant Duncan Slater, who lost both of his legs in a car explosion; Captain Guy Disney, who lost his right leg in a rocket attack; and Captain Ibrar Ali, who lost his right arm in a roadside attack.
Nine members of the international teams that competed in the South Pole trek last December will join them.
Captain Ali told the London Evening Standard newspaper: "The long runs are often very similar to when I was pulling my pulk during the expedition. It's a solitude that is quite nice because I find it's very simple to just switch off. I'll be hoping to make it around the 26.2 mile course alongside my 14 comrades."

Britain's Prince Philip is concerned about mice damaging the Royal Collection.
The 92-year-old royal asked a bizarre question about the insurance of the royals' trinkets - including paintings, historical photographs and more - during a visit to Lloyd's of London with Queen Elizabeth yesterday (27.03.14).
The royal couple visited Lloyd's to celebrate its 325th anniversary.
Philip asked insurance group Hiscox's chief underwriting officer Paul Lawrence: "Is the Royal Collection insured against damage by mice?"
Paul replied: "For you, everything is covered."
Hiscox is in charge of insuring more than a million royal treasures including 7,000 paintings, historical photos, furniture, tapestries, ceramics and books at all royal residences across Britain.
It's not known what spurred Philip's bizarre question and both Buckingham Palace and the Royal Collection Trust appeared dumbfounded.
A spokesperson for the Trust told the Daily Express newspaper: "We don't have any concerns about mice in relation to the Royal Collection."
Queen Elizabeth, 87, unveiled a special plaque to mark her visit to Lloyd's and the royal couple joined chief executives for a luncheon thrown in their honour.

Belgium's Prince Laurent has been taken out of a medically-induced coma.
The 50-year-old royal was rushed to hospital last week after coming down with pneumonia and volunteered himself for an artificial coma two days ago.
However, he has now come out of the coma as his condition has improved.
Royal spokesperson said Prince Laurent - younger brother of King Philippe - is a in a "stable" condition.
Laurent is doing significantly better since being admitted to Cliniques Universitaires Saint-Luc hospital in Brussels and doctors are now encouraging him to eat.
Doctors placed him in an artificial coma in order to improve his condition by giving him antibiotics.
Belgian TV channel RTL said: "An artificial coma would avoid the patient exhausting themselves by fighting against the life-support system."
Laurent's wife Princess Claire - who was born in Bath, England - has been by his side throughout the ordeal.
The couple have a 10-year-old daughter, Princess Louise, and nine-year-old twin sons, Prince Nicolas and Prince Aymeric.
King Philippe visited his brother on Monday (24.03.14) and Queen Mathilde visited on Tuesday (25.03.14).

Kate Bush's London residency has sold out in less than 15 minutes.
Tickets for the 'Wuthering Heights' singer's upcoming 22 concerts at the Eventim Apollo in Hammersmith were snapped up in record-breaking time as fans fought for a chance to see the star on stage for the first time in 35 years.
Kate said this morning (28.03.14): "I'm completely overwhelmed by the response to the shows. Thank you so much to everyone. Looking forward to seeing you all later this year."
The tickets for her 'Before The Dawn' concerts went on sale at 9.30am this morning and are now completely sold out.
The gigs are kicking off on August 26, with seven new dates at the end of September and in October added just last night due to massive pre-sale demand.
Kate's announcement comes 35 years after her 'The Tour of Life' shows in 1979, which had until now been the only concert tour of her career.
The six-week tour took her around Britain and mainland Europe and ended at the Hammersmith Odeon - now called the Hammersmith or Eventim Apollo - the venue she has chosen to return to.

Alexandra Burke is to make her West End theatre debut.
The 'Bad Boys' hitmaker - who shot to fame after winning 'The X Factor' in 2008 - will replace Beverley Knight in the lead role in 'The Bodyguard' from June 2.
The 25-year-old singer is a huge fan of the late Whitney Houston, who played Rachel Marron in the original 1992 movie, and is delighted to be following in her footsteps.
She said: "I couldn't be more excited about joining the cast of The Bodyguard and to play the iconic role of Rachel Marron will be a dream come true.
"I am a massive Whitney Houston fan so to be given the opportunity to play a role made famous by her every night will be a real privilege. I start rehearsals very soon with my fellow cast mates and the brilliant creative team and, with a little trepidation, I am looking forward to our first performance in June."
Alexandra was approached by producers Ian and Michael Harrison about joining the production until the end of its run on August 30 after they learned Beverley was to leave to join 'Memphis'.
Ian told the Daily Mail newspaper: "We saw her, and our creative team met her, and she was fabulous and knocked the songs out of the park."
Tristan Gemill will continue in his role as Rachel's bodyguard Frank Farmer.
The show debuted in London in 2012, and ahead of its opening Alexandra was touted as the favourite to take on the lead role.
A source said three years ago: "Alexandra is torn - the show would be an amazing gig and especially in London while the Olympics are on and it's in the spotlight. But she also has her second album to think about."

Gwyneth Paltrow and Chris Martin are planning to live together in Malibu.
The former couple - who announced they were separating after 10 years of marriage earlier this week - splashed out on a $14 million beach house shortly before confirming their split, and though it had been speculated it had been bought as a bachelor pad for the Coldplay frontman, insiders say they will share the property.
According to the New York Post newspaper, the house includes "two totally separate" living spaces so they are both able to stay close to their children Apple, nine, and Moses, seven.
It had been speculated the 'Fix You' star would live alone in the Californian property because it was bought by a special trust.
A property insider said: "For this property a new trust was created, called Magical Kingdom Land (trust), which signalled something definitely changed between the pair.
"Everything else they have owned together, including homes in London and New York, was bought under Orchard House LLC. It appears that the trust used was different to the firm that Gwyneth is known to be associated with."
Announcing their separation, Chris and Gwyneth said they were "closer" than ever and would always put their family first.
They said: "We are, however, and always will be a family, and in many ways we are closer than we have ever been."
