The Russian beauty welcomed her fifth child on Saturday.

It's a boy! Russian supermodel Natalia Vodianova, 34, on Tuesday took to Instagram to announce the arrival of her newest bundle of joy, Roman, with her partner, LVMH heir and Berluti CEO Antoine Arnault.

"Last Saturday early in the morning, our family welcomed a new baby boy: Roman. A beautiful little shrimp, discovering the world already with the help of his brother and sister, and making Papa very proud," Vodianova captioned the photo. "I am well, even if a bit tired, but ready for the big summer. Thank you to all my friends for their messages and to everyone for their support."

Vodianova and Arnault welcomed their first son, Maxim, in 2014. She has three children — Lucas, Viktor and Neva — from her previous marriage to Justin Portman.

Her fifth pregnancy didn't slow the supermodel down; late last year, she launched the philanthropy-driven iPhone app Elbi, which allows users to donate money and connect with charities and recipients. Vodianova also is the founder of the Naked Heart Foundation, dedicated to the needs of disadvantaged children in Russia since 2004.
