The 20-year-old model teamed up with her boyfriend for the promo clip for his debut solo single earlier this year and she'll always have fond memories of the shoot, which came early in their relationship.

She said: "It was fun for us. We just started dating. It's cute to look back. We were into each other and flirting the whole day."

Though they had a great time, Gigi doesn't think she'll be appearing in more of the former One Direction hunk's videos in the near future.

She said: "Not sure about another. We got one done. I think it's important for artists to change creativity throughout each music video. Maybe in a couple of years."

However, the blonde beauty adores working with her boyfriend, and had "the best time" shooting a spread for Vogue magazine while on holiday in Europe.

She gushed to E! News: "I wish I could be on set with him every day. It doesn't feel like work when he's there.

"It was really fun. We had the best time. It was an adventure to go where we shot it."

And Gigi thinks Zayn makes a great model because he is "so naturally good looking".

She said: "He is a very good model. He's so naturally good looking.

"The problem is he can do anything, he can change his hair colour a million times and looks great. He doesn't need much help."
