The 'Pillow Talk' singer told Complex magazine that he's still getting used to the public interest in his high profile relationship, but in general, he tries not to think about it.
"I try to keep the two very separate. I try to, as much as I can. But there's only so much you can do," he explained.
"I'm learning to deal with it. It's just one of those things now, in the background. I just leave it as a bit of a noise in the background."
Supermodel Gigi starred in the music video for Zayn's debut solo single 'Pillow Talk', which features them cuddling, kissing and generally looking all smouldering hot.
When asked by Complex's interviewer about a part in the video where Zayn and Gigi are smiling at each other, Zayn said: "To be honest, the reason it was used was because we were just messing around. It wasn't even, like, part of the shoot. You know when they say, "action"? They didn't do that. It was just rolling."
Zayn – who quit One Direction last March – previously dated Little Mix singer Perrie Edwards. The pair were engaged before their split last summer.
Just last week, Zayn was forced to deny "throwing shade" at Perrie after a tweet he posted was believed by some to be taking a swipe at his popstar girlfriend.
After Perrie defended her band's tour costumes, Zayn tweeted: "Love how people feel liberated naked .. Read a book liberate your brain."
But after speculation that was aimed at Perrie, he clarified: "This is not shade... Love .. liberate yourself with education and learn to love everyone's expression .. I said love how exactly is that shade? Explanation done."
And Gigi added: "This is not shade... Love .. liberate yourself with education and learn to love everyone's expression .. I said love how exactly is that shade? Explanation done."
