Gigi Hadid and Zayn Malik are ''closer than ever''.

The 21-year-old supermodel and her former One Direction band member beau - who split up last month after embarking on their on and off romance for seven months - are now ''back to normal'' after Gigi reached out a hand to support her boyfriend through their ''dark'' patch.

Speaking to E! News about the 'PillowTalk' hitmaker's relationship, a source said: ''Things are back to normal with them.

''They got through a rough patch that Zayn was facing personally and it started to put a dark cloud on their relationship. Gigi was there for him when he needed her the most and that brought them closer than ever.''

And, the couple are rumoured to be putting all their energy into mending their romance by spending time together and away from prying eyes.

The source explained: ''They have been spending some alone time together lately without the media seeing them.

''Zayn is feeling better with the help of Gigi and many other close people in his life. It's a work in progress for him.''

This news comes after the dark haired heartthrob cancelled his gig at this year's London's Capital FM Summertime Ball, on the grounds he had ''suffered the worst anxiety of my career.''

However, the blonde beauty - who has fronted campaigns for luxury fashion houses Victoria's Secrets, Chanel and Balmain - stood by the musician and was a pair of ears for Zayn to confide in during his tough time.

Speaking previously, an insider said: ''[Zayn] opened up to Gigi about his anxiety the past few weeks. [They] have been through a lot these past few months, but they are really trying to communicate better going forward.

''Zayn really appreciates Gigi even more after this because he sees how much Gigi is there for him.''
