Anne Vyalitsyna is pregnant.
The model, also known professionally as Anne V, took to Instagram to announce she is expecting her first child with her partner, Adam Cahan, who is senior vice president of mobile and emerging products at Yahoo!.
The 29-year-old star broke the news on her birthday yesterday (19.03.15) by posting an image from her ultrasound scan on her account.
She wrote alongside the picture: "On this birthday I couldn't feel luckier, happier & more grateful. @Adamcahan & I couldn't be more excited for you!"
Fellow model Christy Turlington was quick to offer her congratulations to the blonde beauty and shared a snap of herself and Anne together.
The photo, which depicts the Russian model smiling in a t-shirt and jeans, hints that Anne is already quite far along as Christy rests an affectionate hand on her blossoming bump.
She captioned the photo: "Happy birthday to the beautiful @AnneV, and welcome to the sisterhood of motherhood!@everymomcounts.(sic)"
