Victoria and David Beckham's 11-year-old son Cruz is drawing favourable comparisons to pop sensation Justin Bieber after his mother posted a video of him singing a capella.

The short clip shows the couple's youngest son smiling as he looks directly into the camera to perform the chorus of Twista's 2005 rap single Hope, featuring Faith Evans.

Beckham, 41, captioned the video "Super cute Cruz!! with the hashtag #proudmummy. She also tagged husband David, 40, and the pair's oldest son Brooklyn, 17.

"Cause I'm hopeful, yes I am, hopeful for today. Take this music and use it, let it take you away," the youngster sings.

The clip has attracted more than 315,000 "likes" and more than 25,000 comments, with many comparing the youngster to Bieber, who rose to fame at 13 after being discovered on YouTube.

"Little Justin Bieber when he just started...how cute," one user wrote.

" I can't even handle that kind of cuteness!" another commented.

"Great!!! Cruz=Future Singer," another posted.

Here's the original version:

This is the first time Beckham has shared her third son's singing talents with the world.

Cruz's older brothers Brooklyn and Romeo have already followed their parents into the limelight, with Brooklyn carving out a fledgling career in photography and modelling, while Romeo, 13, is a Burberry model.

The couple also have a four-year-old daughter, Harper, whose painting skills recently prompted another #proudmummy moment:
