Karlie Kloss has launched a YouTube channel because she wants to be ''normal''.

The 22-year-old supermodel has posted her first video on the channel - named Klossy - and revealed the reason for her move into vlogging is because her life got ''crazy pretty quickly'' when she was discovered in 2005.

Karlie said: ''The first 13 years of my life were just normal, well, except my height, which has never been normal. In 2005, I was 'discovered' and things got pretty crazy pretty quickly.

''I'd be in second period chemistry one day, and then walking the Paris runway the next. Over the years, modelling has kept me very busy, but it's not my sole focus.''

The Victoria's Secret model - who was recently accepted into New York University - has promised Klossy will give viewers an insight into ''things you never got to see before'' both on-duty and off, and is really ''excited'' about the prospect.

Karlie said: ''I've spent the majority of my life in front of the camera, but not my camera. And that's where this is different. I could not be more excited to share my story, and this adventure, with you.''
