I swear I saw her at the Montreal airport quite a few years ago. I was there for the Canadian Grant Prix. Maybe she is a Formula 1 fan.
Minka wasn't/isn't just a porn star, she is also an escort, private dance and nightclub, gentlemen's club performer, so she was quite likely going to meet a man and/or multiple men and earn some money. After all, Montreal is in Canada/North America, so it's relatively easy to travel to from the USA.
