Style mag GQ has placed Romeo at number 26 on its annual list, just ten places behind dad David.
Selfridges menswear director David Walker-Smith told the magazine: “Romeo is experimental, quirky and fun. His style has nothing mini-me in it. It’s me-me!”
Romeo took career direction from fashion designer mum Victoria earlier this year when he signed a deal for his own fashion label.
The range for children, originally called Bambino Beckham, is set to include sunglasses and a Jonas Brothers-inspired waistcoat.
A source told The Daily Mirror in September: “Romeo has a real eye for fashion. He has strong opinions on what works and what doesn’t.”
