The concoction was apparently dreamt up to satisfy an "A-list" celebrity client who wanted something special for a party. And, according to Francis, the guests were "very happy with the end result."

At least according to her twitter:

just to clarify me and David did not plan that but he guessed it was April fools so jokingly replied, sad that I have to specify that lmao
