David Beckham has defended the decision to allow his 11-year-old son Cruz to release a Christmas single.
"If Every Day Was Christmas" hit the airwaves for the first time last week after being premiered on Capital FM.
The 11-year-old told the radio station: "It's amazing.
"It's two of my favourite things - singing and Christmas - and it's amazing to put those together and the money is going to charity."
But former footballer Beckham, 41, and his wife Victoria, 42, came under fire for allowing their youngest son - who is signed by Justin Bieber's manager Scooter Braun - to enter the music scene.
However, the ex-Manchester United star described the track as a one-off and said it did not signal the launch of Cruz's music career.
Speaking to Good Morning America, Beckham said: "We only realised that Cruz has a cute little voice about nine months ago.
"Scoots has been a family friend for a while. He said 'bring him in, see if he enjoys it'".
Beckham told the US show: "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 which has got a lot of attention."
Beckham added that the whole family were "very proud" of Cruz.
"He came to us with the idea. It's kind of cool, he's having fun," Beckham said.
Good Morning Britain host Piers Morgan was among those to criticise the Beckhams.
