Victoria Beckham is amazed at the differences between her three sons.

The former Spice Girls singer-turned-fashion designer – who has Brooklyn, 10, Romeo, seven and Cruz, four, with her soccer star spouse David Beckham – says the trio are growing up quickly and have little in common with one another.

She told Ryan Seacrest on his KIIS radio show: 'They are so different. I mean you've got Brooklyn who is a real boy, he's turning into a teenager. It takes him quite some time to do his hair in the morning before he goes to school. Then we have Romeo who loves fashion. He likes to go out in a suit with a bowler hat, he's a real fashion lover. And Cruz just wants to break dance every opportunity he gets.'

Meanwhile, it has been reported Victoria has been offered a job styling contestants on 'American Idol' following her recent stint as a guest judge on the TV singing contest.

A source said: 'This is a fantastic opportunity to showcase Victoria's spectacular eye for fashion. She's giving the offer serious thought.'

Victoria has previously spoken about Romeo's love of fashion, admitting he likes to advise her on her fashion range.

She said: "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."
