Natalia dedicated the picture, which she had posted on her Instagram account, to her partner Antoine Arnault, wishing him a happy birthday.
"happy birthday baby from Paolo, Maxim and I. Love you @antoinearnault", Natalia captioned the shot.
The stunning black-and-white picture was taken by Italian photographer Paolo Roversi, who Natalia revealed in a second shot was one of the first photographers to take her picture in 2001.
The 32-year-old welcomed her fourth child, and first with boyfriend Antoine, in May this year.
At the time she announced to her fans: "The baby and I are doing beautifully well to the delight of the proud Daddy. Thank you for all your good wishes, I would now like to pass them on to all who are still expecting. Enjoy every minute of it."
Natalia and her French boyfriend, who is CEO of luxury men's shoe label Berluti, confirmed that they were dating in 2011 after they were pictured kissing on holiday in Ibiza.
The blonde beauty had separated from her husband of nine years Justin Portman a few months before.
Natalia, who has modelled for Givenchy, Calvin Klein, Louis Vuitton, Yves Saint Laurent, Versace, and Chanel, is also a well-known activist, is a founder of the Naked Heart Foundation, a philanthropic organisation that strives to provide a safe and inspiring environment in which to play for every child living in urban Russia.
