After a quick stop over at Fashion Week,Victoria Beckham was already on her way back to the West Coast earlier today. Last night she looked hot in her short sparkly number at the Armani store opening party,where she explained why she's jetting out of NYC so quickly.She said,"I have to leave here tomorrow and go home. It’s [Cruz's] birthday. He said, ‘It’s my birthday after Fashion Week’. I’m training him well." Fashion may be one of Victoria's first loves, but it doesn't come before Cruz's very important fourth birthday.
