My boyfriend added a model on facebook and I'm really confused about it?

[kate]

My boyfriend is a model and so am I, we met during a runway show in France last September and we started our long distance relationship in November. We are both really jelous types and its hard to handle the jealousy when we are so far from each other sometimes, but we do trust each other. My boyfriend is a really confined person and doesn't accept or add much people on facebook so I was really shocked the other day when I saw that he added some model. By the looks of it, they've never met each other or worked together so I don't know how they became friends... She seems to look more professional and experienced than me and as much as I trust him my instincts are telling me theres something weird about this. I feel awkward confronting him about it because then he'll know I check his profile sometimes and it'll seem weird, I also don't want to start a fight. Should I confront him about it or not? If so, should I wait to confront him in real life when i see him in 20 days or online now... please help me... I'm so confused
