Kaia Gerber says starring in her first photo shoot with her brother was "amazing".
The 13-year-old model - who is the daughter of Cindy Crawford and Rande Gerber - has revealed she loved posing alongside her older brother Presley Gerber, 15, for a photo spread for the upcoming seventh issue of the CR Fashion Book.
Kaia - who was recently signed to IMG Models - said: "It was amazing for [Presley and me] to do our first shoot together with such an incredible team.
"Bruce Weber is an amazing photographer, and Carine Roitfeld's style - and everything she does - is gorgeous. It felt unreal to have two people like them together on set."
In the first snap from the spread Kaia is the spitting image of her model mother in a bubblegum pink dress while the second sees her joined by her brother Presley and model Garrett Taber as the threesome show off their best blue steel poses while sat in front of a sports car.
Speaking about working with the siblings, Roitfield told Us Weekly: "I found [both Kaia and Presley] to be very polite, and with a very good background, for their age.
"I am not that surprised - I have known Cindy since my days at Elle magazine."
Roitfield also stated that although she's thrilled Kaia has landed a modeling contract, she had no doubts about including her non-model brother in the shoot.
She added: "Beauty runs in their blood - Presley's even got Cindy's same mole on the cheek.
"I wanted to focus on both the kids. To me, that makes the full story more interesting. I like the idea of the brother and sister duo born with fashion in their blood."
Kaia has since taken to her Instagram account to post her solo image from the shoot alongside the caption: "A first look at the @CRFashionBook, Issue 7!! Shot with the bro @PresleyGerber. Full issue out in September. Photo by: @Bruce_Weber Styling by: @CarineRoitfield #CRFashionBook (sic)"
And Cindy has gushed about how proud she is of her children on Twitter, re-tweeting the image of Kaia and Presley and writing: "Love this, @KaiaGerber & @PresleyGerber! (sic)"
