Russian supermodel Poly announced the news in a picture online, cradling her growing baby bump.
The 27 year-old model, who has graced runways and international magazine covers for almost ten years, made the announcement this week that she and her husband are expecting their first child together.
Taking a modern route of releasing the news by posing for a picture and uploading it to picture sharing site Instagram, Poly simply added the caption: "baby on board".
Poly married Dutch businessman Peter Bakker in April 2011 during a ceremony in Saint Tropez.
The couple have yet to reveal Poly's due date or the sex of their baby.
