Gigi Hadid loves being in the fashion business with her sister Bella.

Gigi, 23, and Bella, 21, are two of the most in-demand models in the world and big sister Gigi admits it's great to be able to share a profession with her younger sibling.

In an interview with tennis superstar and close friend Serena Williams for V Magazine, she said: ''I absolutely love it. It's very rare to have what Bella and I have in fashion, what you and Venus have in tennis.

''I feel very lucky to be able to have a piece of home in my work environment. We are each other's biggest fans. It has been a huge joy of my life to watch my little sister flourish, and to help when I can!''

Despite both being in the same line of work, Gigi revealed the two sisters aren't actually too competitive in that regard - and any sibling rivalries come from other areas of their lives.

She added: ''I would say that out of everything, Bella and I are the least competitive about our careers. We are more competitive about holiday cooking.''

The famous pair both grew up riding horses, and while Gigi admitted they would have enjoyed pursuing their equestrian sport ambitions.

She said: ''We both would have definitely been very happy going that route as well, but I think fashion opens a lot of doors to different and unique experiences and opportunities. I get to work with horses a lot for shoots and that always makes my day. Bella and I recently got horses again and ride at our farm whenever we aren't working.

''Having that as a getaway is such a blessing. I would love to compete again one day when I have more time!''
