The proud dad shared a clip of Cruz singing the infamous 'Cups' song from the hit film 'Pitch Perfect'.
Together with a spot-on routine, Cruz seamlessly showed off his vocal skills with slight encouragement from his mum and dad in the background.
"Look at my little man go," the dad-of-four wrote on Instagram.
"Ridiculously cute and the enjoyment in his face whilst doing it just makes us smile."
This is the second time the 11-year-old's singing talents have been brought to light.
Victoria Beckham recently shared the first video of Cruz singing the chorus to Twista and Faith Evans song 'Hope' on Instagram, that sparked a flurry of positive comments.
"Super cute," the mum captioned the video, adding a #proudmum hashtag.
