This looks like so much fun – Happy Birthday to Khai’;’you were born to be a girl dad, the coolest’. Zayn rarely features Khai on his social media, but back in February he gave a rare insight into fatherhood as he revealed he gave Khai £500 after she lost her first tooth.Speaking on the Call Her Daddy podcast, the singer left host Alex Cooper speechless as he shared the outrageous amount of money that he gave as the tooth fairy.Zayn said Gigi told him off after giving their daughter that much money but defended his actions stating that he ‘works his a*** off’.He said: ‘I’m raising her in an environment that isn’t the same as everybody’s, her dad is a pop star and her mum is a model and certain things that she does in life might not reflect what other people’s understanding of reality is.

Happy birthday to the princess’; ‘In the world of celebs and wealth it’s so lovely to see a normal kids birthday party”So I think I gave her a bit too much money from the tooth fairy – £500. It’s her first tooth and her mum gave me s*** about it but at the end of the day I work my a*** off and I should be able to give my kid what I want to give her.Alex gasped: ‘Hold on, I may have to agree with her mum on this. £500 for one tooth! That’s so crazy, but also everyone is going to be so jealous right now.”She’s my first kid, give me a break somebody please,’ Zayn said.’People in general look at it a certain way but at the end of the day I was lucky if I got anything for my teeth and I’ve worked really hard for everything I have earned so I don’t feel like I have to answer for them things.’He added: ‘There’s definitely a feeling of ‘”I didn’t get to do this so I want you to be able to feel this.” I overcompensate a little bit too much for that.’Speaking about little Khai’s aspirations for the future, Zayn said she wishes to be a K-pop star.He said: ‘Honestly I just hope that she gets to do in life what she wishes to do and she’s happy.’She definitely wants to be a K-pop star, she’s big into K-pop. I’d like to keep her away from it but at the end of the day if she’s happy, I’ll support her.’Me personally I would like to keep her away from some of the headache that this job entails.’Last year, Gigi offered rare comments on Zayn, as she opened up on their co-parenting arrangement to Vogue.’Zayn and I do our custody schedules months in advance,’ she revealed. ‘That doesn’t mean that it doesn’t change here and there, but we help each other out and have each other’s backs.’The star added that she and her ex have entered this phase of their partnership with ‘love, and a feeling of camaraderie’.Their six-year romance came to an end after Zayn got into an altercation with Gigi’s mother Yolanda Hadid, for which he received 360-day probation and was ordered to complete anger management and domestic violence programmes.Referencing the incident, Gigi lamented: ‘There is the hard part of the world knowing this much, and thinking they know everything. And at the end of the day, we’re not interested in giving everyone our whole story.’What we are interested in is raising our daughter together. With so much respect for each other, and not just as co-parents, but what we’ve been through together.’
