Who is the hottest princess in Ooo?

Finn Mertens has always been a major hero of mine, he is a lawful good character who embodies many strong Judeo Christian values, however one thing that has bothered me about the character is that he is far too promiscuous with many of the princesses in Ooo. I think it would be far healthier if the character settled down committing himself to a monogamous relationship with only one of the princesses in the show, problem is there are quite a few princesses in the land of Ooo, which one do you think is the hottest and thus the most fitting vessel for Finn's seed?
