I thought it was fine and sort of sweet. She was just excited and happy. As far as her sexuality, she was trying to acknowledge that she is gay, but probably only because her former partner and their children were present and she wanted to express her feelings to them on such a special occasion. She’s gay but she is single. She and her long-time partner are still friends, but have broken up. She also was just talking a lot about the fact she’s spent her entire life (literally since early childhood) in front of the cameras. The part addressed to her mother was because her mother has late stage dementia and she was hoping if she told her she loved her three times that one of them might register.
Rambling, yes. A combination of excitement, nerves, emotional, yes. A bizarre ramble? No.
