Erm well this is a challenge but I would say throw your plan out the window and try something like this, which was the first thing that came to mind.
Ok so firstly you need to ditch the 7 if shes meant to be like a 'date'. If shes just going as a friend then introduce her to someone and say I'm gonna go get a beer or whatever then your free.
Now I'd imagine that if theres semi-celebs and a model there lots of people are going to know her. Fair enough if you wanna get in the line of guys that are trying to pull her but personally I'd look around. Theres GOT to be some hotties at this party and then that gives you your opening lines...
Approach and...
"Hey are you the model that everyones talking about"?
"no"
CONVO from here and you've already said she looks like a model... DHV and move it from there.
You even have negs...
"Oh hey are you the model everyones talking about?"
"no"
"oh thats cool was about to say I've never seen you before"
Those are rather pants but I'm sure you can get more creative with it. Best thing imo with the model is just plain ignore her, talk to her and just plain pretend you don't know who she is. Maybe get a bit self rightious and act like your the celeb "Hey can you pass me a beer please?", "hey I hope your enjoying the party" (as if your the one throwing it) DHV by the bucket load... raise yourself a few levels up the social ladder then bring her down a few notches then when your level just go for the kill.
Personally I think its a massive challenge but one you'll learn from one way or the other. I'd be interested to see how you get on, once the party is done with I'd be interested in knowing who she is out of interest
Anyway good lucky buddy and hope to see a FR a bit later
