Kendall Jenner has denied that she is dating Justin Bieber.

The 19-year-old model has rubbished rumours that she is seeing the 'Baby' hitmaker.

When asked if the pair were an item, she said: ''He's a longtime friend of our family.

''Everybody loves to assume things, but no.''

Kendall also insisted that she would rather focus on her career than be in a relationship.

She was asked if she was dating anyone, to which she replied: ''I'm not. I'm truly focusing on my career. If it comes it comes.''

Meanwhile, the 'Keeping Up With The Kardashians' star also revealed that she had to ''work pretty hard'' to become a model and didn't want to use her family connections to break into the fashion industry.

She said: ''I'm not trying to use a family name or anything.

''In reality I worked pretty hard for this... It wasn't like I just got it magically and it just happened.''

Kendall also insisted that she didn't ''ban'' her sister, Kim Kardashian West, from coming to any of her fashion shows.

She added to ABC News's Nightline: ''It was more of a mutual understanding.

''I think that if my sister was sitting front row and my sister is who she is, I know this sounds kind of weird but it would have almost taken the attention away from what I'm trying to do on my own.''
