Happy Birthday?

It's your birthday and there's a huge birthday present standing in your living room. It's from your best friend. And on it only a note. 'Happy birthday. Have some fun on your special day. I got you a suprise. Just knock on the top and... surprise!' You knock on the present and... The lid lifts. It's a exotic dancer but that's not all. You know that dancer. It is... Your best friend? Your ex? Your current partner? Or someone completely different? Pick your surprise.
