I am the most pretty cupcake in the shop
I am the most fancy dress in the boutique

I am the most pretty girl in the town
I am the hottest man in the country

I am the richest of all the richest
I am the Lord of all the Lords

I am the perfect other half you ever want
I am the perfect life you always wish for

I am the most desirable thing everyone asks for
Yet I am the most expensive of them all

Can you guess what am I?
Or moreover who I work for.....?
