Well, I think there are no other children although I would like to see more Elvis kids,hehe (especially males lol)
I think he was careful when it came to that, but I also agree with someone else discussing this topic who said that there sure were some 'careless' moments too...
Elvisjr or Desiree are just claiming that are his kids but there are no official DNA tests done and I personally don't believe in it. Elvisjr doesn't look like Elvis to me at all.
So, for now, Lisa-Marie is the only Elvis' child
Hugs to you all,
