Model Heidi Klum is going to launch her new brand of lingerie in January 2015.

Klum has replaced Elle Macpherson as the creative director and ad campaign model for New Zealand-based company Bendon, which is now rebranded Heidi Klum Intimates, reports dailymail.co.uk.

Klum has worked as a Victoria's Secret model for 13 years, and she wonders how far the world of lingerie has come over the years.

"It's almost like with the iPhone, how they always come up with something new and there's always a new technology. It's the same thing with bras too, there's always something new...the underwire and the padding has changed, and things are seamless," said the mother of four.
