I didn't take the time the read the whole thread, but here is what I have to say about this.
I know next to nothing about the Luxembourg royals, and I only know about Louis and Tessy having this baby because I was browsing through a tabloid waiting to go to the dentist the other day. I was searching for things about Michael Jackson, but I found no crap about him, thank God, but I found this story instead.
Having a child before marriage isn't a problem to me as long as the parents are together. So the important thing for me is... Are Louis and Tessy still together? And even if they aren't together anymore, I hope, that little Gabriel will become a prince just like his father.
