Cruz Beckham came up with the idea to release a charity single.

David Beckham has revealed his 11-year-old son - who he has with wife Victoria - was inspired by his parents' charitable nature to give back with his track 'If Every Day Was Christmas'.

Speaking on Good Morning America, the retired sports star said: ''The amazing thing about this, we only realised Cruz has a cute little voice about nine months ago. Scooter has been a family friend for a while, so he said to bring him in, see if he enjoys it.

''For us, we always want in our children, we always hope they're listening to us or pay attention to us as parents, so we do a lot of work for charity for obviously Unicef and my wife does for the UN. And Cruz came to us and said 'How about I do a Christmas song for charity? And all the proceeds go to charity.' There's nothing more to this than that at the moment.

''He's 11-years-old, he's still at school, he's concentrating at school. That's the most important thing. But he wanted to give back and he's done this amazing little Christmas song that's got a lot of attention. And you know we are very proud of it. He came to us with the idea. It's kind of cool but he's having fun.''

Meanwhile, a source previously revealed Cruz isn't planning a full-time music career yet.

They said: ''Everyone has gone totally mad over Cruz's little Christmas record. But that's all this ever was - just a kid who loves to sing doing something for his local radio station's charity. Cruz is intent on staying at school and being a full-time pupil, not becoming a pop star.

''Everyone got swept away on a wave of pushy parents, record deals and albums, but the truth is it's so much more simple. There is no album or touring with Justin Bieber, as has been suggested. It's just a one-off Christmas song.''
