What did this Iben Detlefs see in Joachim?

I think she had a luckey break when he broke it off.
Let me guess.... He is a prince?
To be fair, she seemed really devastated when he broke up with her, maybe she really loved him for himself (strange taste...). It must have been hard for her to see Alexandra´s face on covers of magazines for years.
I remember that she wasn´t a rich girl and when they attended big parties, she made her own clothes - and looked stunning in them. I was very impressed with that.
