The former Spice Girl shared her pride in her son as she posted a photo of Cruz strumming along on his guitar.
"My babies turn X Kisses from Hollywood XVB," Victoria wrote on Instagram.
Cruz has been taking guitar lessons
Cruz looks set to follow in his famous mum's footsteps. The eleven-year-old has already shown promise with his musical talents and is rumoured to be taking up guitar lessons in a bid to reach stardom.
An insider previously told The Sun: "Cruz has a natural affinity with music and he's been desperate to learn the guitar. He's had lessons for months and is constantly strumming away, singing along.
"Obviously he still has far to go, but there's certainly potential there. He's got a natural stage presence."

Cruz is even said to have caught the attention of Justin Bieber's manager Scooter Braun. It is unclear what guitar the schoolboy was playing on in the Instagram photo, but it may well have been the signed acoustic guitar that Justin gifted him a few years ago.
Cruz and his older brothers Romeo, 14, and Brooklyn, 17, were each given guitars from the Sorry singer after he heard the Beckham children were fans.

Cruz's talents first came into the spotlight earlier this year when Victoria and David started sharing photos and videos of their superstar son.
The young boy has blown fans away with his renditions of Anna Kendrick's Cups and Twista and Faith Evans' Hopeful. Even his dad David was impressed.
"We didn't realise what a great voice he had, actually," the retired footballer told MTV. "He loves to sing so we knew he had a pretty good voice but when he did the Cups thing, that was kind of amazing. He's definitely got a little bit of talent there."
