Jennifer Lopez and Victoria Beckham attend the Marc Jacobs show

Jennifer Lopez and Victoria Beckham attend the Marc Jacobs Spring 2009 fashion show during Mercedes-Benz Fashion Week at the NY State Armory on September 8, 2008 in New York City

Posh had been rocking her bob for over a year – it was getting stale, it was time for a change. And of course, in true Posh fashion, she chose to debut the change in dramatic fashion, pretty much stealing the spotlight at the Marc Jacobs show in NY for fashion week alongside Jennifer Lopez.Check them out upon arrival:

Victoria and the Lopez pretty much eclipsed everyone else, engaging in a fierce pose-off for photographers in contrasting black and white. Perhaps they even eclipsed Marc Jacobs? Will Marc appreciate being eclipsed? Doubtful

Jo Lo on the other hand looked fantastic in her white outfit sliming down back to her normal size after giving birth to the twins.
