Russian supermodel Natalia Vodianova has given birth to a baby boy.
The 32-year-old welcomed her fourth child, and first with boyfriend Antoine Arnault, in the early hours of Friday morning.
The Calvin Klein model proudly announced the news on her Instagram and Facebook pages by posting a heart-warming photo of her newborn baby son.

"Last night at 2.45am was born our baby boy Maxim, living up to the definition of his name: he was born an incredible 4.2kg and 55cm!" wrote Natalia next to the image.
"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 women who are still expecting. Enjoy every minute of it."
The sweet snap shows Natalia and Antoine cradling their first child, who is dressed in a white and grey striped babygro and holding his foot up in the air.
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.
