Hollywood's next generation turned out to celebrate Romeo Beckham's 6th birthday in LA yesterday.

Posh called on her A-list friends, including Project Runway host Heidi Klum and Gwen Stefani's rocker husband Gavin Rossdale, to bring along their children for a party at Universal Studios.

Supermodel Heidi arrived with her daughter Leni and son Henry, while the former Bush lead singer had toddler Kingston in tow.

Former Spice Girl Geri Halliwell also attended the party with her redhead protégé Bluebell rounding out the pint-sized pack.

Birthday boy Romeo slipped on his Batman cape for the occasion with Cruz proving quite the little character in a Power Rangers suit.

But Victoria was not to be upstaged, standing out from the crowd in a bright orange dress and towering heels.

David Beckham was absent from the party - he is currently training with the England squad.

Meanwhile, Victoria is gearing up to will launch the latest collection of her dVb brand at New York Fashion Week later this month.

She says has been working very hard on the upcoming line, which features a range of glamorous dresses.

She says: 'It’s almost like my fourth child.'

But her enthusiasm isn't exactly shared by her husband.

She added: 'I think sometimes David thinks I’m a bit nuts. I get very excited about rivets and buttons and fabric that he doesn’t really understand.'

'But he supports me and I think that’s important in a relationship.'
