I think the escorting rumours are extremely far fetched lol. Being thin and pretty gives you access to these types of places/parties. It’s more likely that people just hire boats and clubs for parties and they get invited, that’s how it works. Any boat party I’ve been on the food is supplied and it’s open bar, girls get invited for the day because it’s the done thing/so men can boast or impress others that they’ve invited. You’ll also be invited if you’re a friend of a friend, she knows lots of people.
The majority of Drinks and dinners are free at events or parties but she’s not actually over there on some 50 year old man’s dime.
