This is last night's attempt, I'm not happy with it at all, doesn't look like her. I've concluded that I shouldn't try drawing whilst drinking!
As a result I've spent a while today trying to get a better likeness but the picture I've been working with was too old and small - it really emphasises what all that cosmetic surgery has done for her image - the nose is quite accurate for the picture I had. After a while looking on the internet, I came up with a better likeness, but she isn't smiling as I found it hard to find one of her smiling, then I remembered she tends not to! Anyway my best result, so far, today is this one seen below. 
I think I'll try a few more later, but without the alcohol.
