There was a surprise addition to the show last night, the final of New York Fashion Week.

Reality star turned model, Kendall Jenner, the 18-year-old daughter of Kris and Bruce Jenner and Kim Kardashian's half-sister, made her high-fashion debut in the designer's Fall 2014 show.

The rumoured girlfriend of Harry Styles wowed as she strutted out on the catwalk in a very sheer top, cropped bobbed wig and bleached eyebrows.

Kendall, who signed with The Society Management in November 2013 (the agency that represents Liu Wen, Adriana Lima, and Lindsey Wixson), has made no secret of wanting to move away from her reality TV past and into high fashion modeling.

'I don't think some people take me very seriously,' she said in an interview last year. 'When I started off, I was way more of a personality in modelling and it wasn't like, what I wanted to be exactly.'

It seems her dreams are coming true, as she looked every inch the catwalk star last night. 'I just recently turned 18, so this is my big kick-off to start and grow my career,' Jenner told Into The Gloss backstage at the show.

'The New York fashion scene is crazy, madness, but I love the energy. I love everything about it, like the hair and make-up today, it's incredible. I've never had my eyebrows bleached; I don't even look like myself!'

Half-sister Khloe Kardashian took to Instagram and Twitter to show off her pride of Kendall’s biggest runway show to date, writing, 'My baby sister killed it today walking in the Marc Jacobs fashion show!!! Kenny you are so dope to me!!! Congrats my baby!!! #NYFW #MarcJacobs #ProudSis.'

Stars who caught Jenner on the catwalk last night included Fashion Week fan Joe Jonas, (fellow MJ model) Sofia Coppola and 12 Years A Slave actress Sarah Paulson.

We've recently seen Miley model for the designer, so could a Marc Jacobs campaign be in Jenner’s future?

Future brother-in-law Kanye will be so pleased...
