Victoria Beckham is said to have convinced her soccer star spouse to create a collection of men's suits and evening wear and he is now working on an autumn/winter 2011 series of garment after giving in to months of requests from the singer-turned-fashion designer.
A source said: "Victoria has been trying to persuade him to do it for a while and he's finally succumbed.
"She's reassured him that he has an eye for fashion."
Victoria, 36, is delighted with her 35-year-old husband's efforts so far.
The source added to the Daily Star newspaper: "David is hoping to produce a range of men's couture clothing of fitted suits, smart day wear and an evening range - and Victoria thinks it will go down a storm."
Though this is David's first time working with Victoria, the former Spice Girls star has previously spoken of the enthusiasm Romeo, her seven-year-old son, has for her career.
Victoria - who also has Brooklyn, 11, and five-year-old Cruz with David - said: "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."
