Although the 19-year-old singer's former girlfriend has moved on with the hunky 'Pillowtalk' hitmaker, Cody insisted that he just wants her to be happy and isn't upset by seeing them together in the media.

Cody told Entertainment Tonight: "It's just kind of the natural way things go. You're going to expect that kind of stuff. I've kind of been going a different way, taking a little time for myself just hanging out and keeping it low key, and working on my music.

"But I'm always very happy for her and her career and that type of stuff. I know how hard she's always worked to kind of get to the point in the modeling industry that she's at now, and I couldn't be more proud of her. We still talk every now and then. It's nice."

Gigi, 20, and Zayn recently starred in a joint photoshoot for Vogue, showcasing their relationship and she also appeared in 23-year-old Zayn's music video for 'Pillowtalk'.

And previous reports have suggested the pair are "in love".

A source said: "Zayn and Gigi are getting serious. Gigi was so excited when Zayn asked her to be in his music video. They both acted very professional on set but it was very obvious that they were in love.

"They couldn't stop flirting with each other. Gigi and Bella [her sister] really like the fact they are in music videos with their boyfriends ... This relationship is very different then when she was with Jonas. Her friends think this is going to last!"
