My absolute best friend.. Born the same day as my mum and the same as INTERNATIONAL WOMENS DAY! A Surprise? No.. They BOTH LOVE WINE and cheese and being fancy and are the craziest two people with the biggest hearts I know.. I searched for over an hour to find the picture of us hanging from a tree singing Mariah Carey together but I think she has that hidden for my birthday.. I then looked for her most embarrassing photos but gone they are.. Blue eye shadow and "ladies" in metal across her belt are a thing of the past... I love you @celestegant you are my best friend. X
