Look at that perfect little baby foot! It belongs to a young man named Maxim, the fourth child of Russian supermodel Natalia Vodianova.

Maxim is Natalia’s first child with boyfriend Antoine Arnault, whom she’s been dating since 2011. She revealed the big (literally!) baby news on Instagram on Friday, May 2:

"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!" (That's about 9 pounds, 2 ounces.) "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 S."

Very sweet! Natalia, 32, is no stranger to this experience. She actually gave birth to her first child, son Lucas, when she was 19. She also has two other children, Neva, 8, and Viktor, 6½, with ex-husband Justin Portman.

But Maxim is Antoine's first child, and the couple's first child together. “Giving a little brother or sister to Natalia’s three wonderful children is something we wanted so much: AND NOW IT’S HAPPENING!” Antoine wrote on Facebook in November (via People). He must be so excited right now!

Antoine is the son of LVMH's CEO Bernard Arnault, and heads the luxury brand Berluti. Natalia is one of the world's highest-paid supermodels, taking third on Forbes' list in 2012, after Gisele Bundchen and Kate Moss, with annual earnings of $8.6 million.

Congrats to the growing (and gorgeous) family!
