Australian lingerie model Miranda Kerr has shown off her baby bump in a new advertising campaign for her organic skincare range.

The model announced she was expecting the "Pirates of the Caribbean" star Orlando Boom's baby last month, just weeks after they exchanged vows in a secret ceremony.

Dailystar.co.uk reports, the couple has kept a low profile since they confirmed the news, but Kerr was thrilled to be snapped with her growing bump in an ad for her Kora skincare line.

In the video, Kerr is seen wearing a simple vest and leggings whilst relaxing in a variety of yoga positions.
