Summit EntertainmentAccording to OK! magazine, Robert Pattinson recently purchased a "promise ring" for his rumored, miserable lover Kristen Stewart. I'd like to say that promise rings are really dumb, but in this case it might be the right choice. They are both way too young to be getting engaged, so at least he seems to realize that. Nobody should get married until they are at least in their 60s. I also have my fingers crossed that one day they'll stop making those annoying Twilight movies, and when they do I bet these two will snap out of the vampire love they think they're in. I'm sure Rob's intentions with this ring are good, but I hope he doesn't think it's going to put a smile on her face. That's just not possible.
