Madonna performed her "Madame X" in Philadelphia. Her tour continued at the Met Philly Saturday night and Sunday night. It's a late night show by design. She returns Tuesday and Wednesday night, starting about 11, singing a few hits, but the heart of the show is her Madame X music that is a type of mournful Portuguese music, along with her propulsive rhythms. Cher took her "Here We Go Again" tour to the Wells Fargo Center Friday night. She came out in her first fabulous blue outfit and the crowd went wild! "How do you like my blue hair?" she asked. I love her! You can see video of her performing on my Facebook page, @valerieknight01, on Instagram, valerieknight. Jennifer Lopez hosted "Saturday Night Live", talked about her fabulous 50th year in a tuxedo, which she ripped off to display her iconic green Versace dress that she wore so many years ago. She still looks terrific. Click below to hear all the details in the Show Biz Buzz!
