I've met lots of cool people in my job but honestly this wins hands down... I've loved Sarah Jessica Parker since I was old enough to watch Sex and the City. I begged my mum for a necklace that read 'Alexandra' just like Carrie's and you wouldn't believe how many Carrie outfits I tried - and failed - to recreate... I was so delighted to meet her today and every time I look at this pic my inner teenager screams!
