Cruz Beckham has made his official musical debut! The 11-year-old son of Victoria and David Beckham released his first single -- "If Everyday Was Christmas" -- on iTunes on Wednesday.

"#IfEveryDayWasChristmas out now on @AppleMusic!! All proceeds to @makenoise," Cruz tweeted, promoting the British charity.

Cruz's proud mom also posted a video of his backup choir, writing, "Love a choir at Christmas!! So proud of @CruzBeckham Thank u @RodneyJerkins X VB #IfEveryDayWasChristmas @AppleMusic."

But not everyone was pleased with the youngster's decision to release new music. "Good Morning Britain" co-host Piers Morgan slammed the Beckhams on Wednesday's show.

"I think your children should go through schooling if you're famous parents, without being pushed into the commercial world too early," he said, after holding up a bucket and saying he wanted to throw up into it over the news.

The outspoken talk show host also took to Twitter to continue his tirade against the famous family, writing, "They deliberately exploit their family for commercial gain. We are thus all entitled to comment," and added, "I'm trying to protect Cruz Beckham from his fame-hungry parents."

Justin Bieber's manager, Scooter Braun, got into the conversation, slamming Morgan on Twitter.

"He is an 11 year old who wanted to make a song to help other kids," Braun wrote. "Once again Piers shows why he is a jacka--and why his show was cancelled. Some people in this world make a living out of finding the worst in every situation. It means they have a career.. not class. Just a career."

He went on to personally call out Morgan, writing, "@piersmorgan how about you match him dollar for dollar to the charity? Instead of criticizing step up and help these kids the way Cruz is."

Morgan replied, "Stop pretending this is about charity when it's about promoting Brand Beckham & making YOU a ton of money off another young kid's back. Only one massive hypocrite around here, Scooter, the guy using a kid to line his pockets. Again"

The Beckhams have not publicly responded to Morgan's comments, but have long been supportive of their son's blossoming music career. David first posted a video of Cruz singing Anna Kendrick's "Cups" in April, which sparked fan interest in his Bieber-like voice.
