Gisele Bundchen's five-year-old niece has become a fashion designer.

Duda Bundchen is creating a line for Brazilian children's clothing company Brandili Mundi - who she has already modelled for - and the brand has confirmed she even helped pick out details she liked for the collection.

Germano Costa, commercial and marketing director of Brandili Textil, told Forbes ''She told us about her preferences on prints, cuts and details, and based on the briefing we received from her we came up with a collaborative collection.

''The pieces were all approved by Duda, whose romantic inspiration will No Doubt catch girls' eyes.''

The line has been created and produced with eco-friendly materials, and is expected to his stores in the South American country in June.

She will also continue to be the face of the brand until 2013.

Gisele and husband Tom Brady are one of the highest earning couples in the world, and in addition to her modelling work she also has her own skincare range Sejaa and hotels.
