I just watched Austin Butler's speech after winning a Bafta award for his role as Elvis. He did not say anything about Lisa Marie, or honor her. He just said he wanted to thank the Presley family, hoping that he had made them proud.
Another thing that I don't remember having mentioned is that Janet Jackson announced late last year she is going on tour this year, calling the tour "Together Again", and I don't think that is coincidental. So are MJ and Lisa Marie back together, enjoying their privacy?
