Pivovarova has given birth to a baby girl, she tweeted on Sunday. It's the first child for Pivovarova and her photographer husband, Igor Vishnyakov.
Pivovarova is a high-fashion favorite who has walked for labels such as Prada, Rodarte, Valentino and Chanel, fronted campaigns for the likes of Miu Miu and Giorgio Armani and made her big-screen debut in 2011.
Of course, the busy Russian model took time off of the runway while she was expecting. But just last week, before the baby arrived, Pivovarova made sure to strike the requisite maternity pose: a stunning topless pic, shot by Vishnyakov, of her growing belly, the first anyone had seen of the bump.
Just days after tweeting the photo to her Twitter followers, Sasha tweeted on Sunday morning, "It's a beautiful baby girl #vovarovaholic :') ♥"
Congrats to the happy family!
Today is my first day celebrating mother's day as a mommy! Happy mother's day to all mothers around the world :) Love, Sasha.
