Wonder who is behind Victoria Beckam's posh designs? it turns out be her seven-year-old son Romeo who helps the pop star-turned-fashion designer work on her clotheline.

Beckham, who has three sons, Brooklyn, 10, Romeo, seven, and four-year-old Cruz with soccer star husband David Beckham, said that her middle child has a huge interest in fashion and loves coming to work with her, Harper Bazaar magazine online reported.

"We had dinner last night and Romeo wore a suit with a little shirt and tie. That's what he would wear every single day, he's so into fashion. The other boys are all about going to the beach; he's not interested. He's like, 'I want to go to work with mummy,' and he sits there going through the collection, feeling the fabrics, giving his opinion. He loves it," Victoria said.

The 35-year-old designer has previously admitted that she lets her children influence her decisions on what to wear.

"My kids are my best style advisors because they are so honest. I remember one time I was wearing a Chanel cape and skinny jeans and I walked down the stairs to see my sons and they said, 'Oh my God, mummy, you're Batman!'," Victoria said.
