"Everything is falling into place with his career but he isn't in a rush to put music out yet.
"He is working with Tap to make sure there is a plan in place to give him the best possible launch as a solo singer. His parents' fame means there are big expectations and he has a lot to prove. But the most important thing is that everyone insists his voice is better than his mum's."
In February, Cruz - who made a bid for chart stardom with festive single 'If Every Day Was Christmas' in 2016 when he was just 11 years old - revealed he had been working with producer Poo Bear, who has previously penned a string of tracks for Justin Bieber.
Cruz said: "We've just been in the studio a few times and made some songs together."
The youngster has been writing about "personal experiences, real experiences".
As well as singing, Cruz has taught himself the guitar, piano, and drums and is open to learning more in a bid to strengthen his ambitions.
He added: "I even learnt how to play the mandolin for a song I wrote.
"I don't think you ever stop learning, but I'm taking my time seeing what happens."
