Of course they will get married. I don't think they want to carry the title of "having a baby born in wedlock". I am wondering if I am psychic(I sure wish I was) because I still remember that I had a dream of them getting married awhile back. It was the ancient way(like in Wuxia series) of getting married.
I really hope that he will share at least some photos with us. I personally don't think he has anything more to hide since he has revealed that he is with Kelly now and has a baby. So what more is there for him to hide??
