Just been to see Whitney at the O2. Now I love the Whitney that we all knew but this concert was appalling - when she did sing - she couldnt. I expected to be dancing in the isles to all the old and new Whitney hits - but it was appalling. She did a long dedication to Michael Jackson - I wasnt there to hear her talk about him as much as I loved him - I cannot find the words to say how appalling this was and how upset I am..My husband bought 4 tickets for us for Christmas and we have been looking forward to the concert since.
