I too thought she looked tired and a little more subdued than usual and suspect that she appeared as a response to media reports. Strangely, I also thought she looked younger than usual and wonder why this could be! I hope she's enjoying the tour - I haven't been but I've bought their CD and think it's great. She's obviously taking on a lot more responsibility singing wise than previously which must be onerous as she's not really done much performing singing wise for 20 years. However, she's surrounded by her family and I doubt she could ask for better support.
I look forward to seeing her back on Loose Women in a few weeks and also to receiving the Nolans DVD in my Christmas stocking!
