The blonde, who has modelled for Victoria's Secret, Chanel and Marc Jacobs and hosted reality TV show Holland's Next Top Model, suffered a fractured skull and vertebrae in the accident off the coast of the Italian island of Ischia and had to be airlifted to a hospital in Naples.

Her father Wilfred Sturm tells Dutch newspaper The Telegraaf his daughter had a "hairline fracture in her skull" but there was "no bleeding".

The 33 year old, who became a mother in July (15), is an ambassador for the Dutch Red Cross Foundation.
