Skinny Girl Margharita's In Australia?

Bethenney Frankel from Real Housewives of New York, celebrity chef, mum and star of Bethenney Ever After brought out the skinny girl margharita a few years back.  She is often seen on her Bravo series drinking one of these on ice.  As a fan of Bethenney, I have often thought how appetising this cocktail looks and would love to sample a drop of the already mixed cocktail of hers!

The only problem is, you cannot get this in Australia!  I've checked the skinny girl's website out and it looks as though nowhere in Oz stocks this tipple.  I am gutted to say the least!

Unless I am wrong and someone out there has found some bottle shop in Oz that do stock this drink, please let me know ASAP!

God, reading through this post I sound so sad!  Maybe I should just make my own from scratch hey?
