The 21-year-old model and her 23-year-old boyfriend love to watch TV and cook together but when they are not slumped on the sofa or whipping up a storm in the kitchen, she loves to admire his toned physique.

When asked what it's like to have the former One Direction star crooning to her with his shirt off, she replied to Allure magazine: "Yeah, that's not hard to look at. I'll never complain about that."

The singer has been known to post the odd scantily-clad image of himself on his Instagram account and while Gigi is also a big fan of the picture-sharing site, she would love to write a book about how best to use social media and "make millions" from it.

She added: "I wish I had a strategy to [social media]. I could write a book and make millions. But I never feel like I'm working when I'm doing social media. I guess I succeeded at it because it came naturally.

"I always want to prove myself and to let people know I'm a good person.

"A lot of people don't realise they're typing this stuff, and that's a lot of negative energy - regardless of whether we see it or not. People just don't realise the power of their judgement."

One area Gigi is keen to prove herself is on a film set, but she is waiting for the right movie to come along, and admitted she has already turned down some "dumb-model roles".

She added to the publication: "I think I'll only do one or two movies in my life, so I want them to be good."

This comes after Gigi recently admitted she will try not to "embarrass" Zayn should he win the American Music Awards' New Artist of the Year prize when she co-hosts the ceremony November 20.

She recently said: "To be the winner's girlfriend, you don't want to embarrass them, but you also want to be super-excited for them. I'm just going to try and not be the embarrassing girlfriend. That's my goal."
