Up first, rumors are circulating that Britney Spears is adding a surprise guest appearance to her upcoming concert roster.  It may be in the works that Madonna will be joining the pop-star at her New Orleans stop in March 09. B-Spears tour choreographer, Wade Robson, did indeed get quoted saying there are talks of Madge making an appearance. And Scarlett Johansson is mixing it up with the British as well. Her rep is reportedly threatening to slam down a lawsuit against the UK-version of Cosmopolitan. The publication put Scarlett on the cover of its January 09 magazine and makes claims about Johansson past relationships as well as her current marriage to actor Ryan Reynolds. The problem here is that the actress\' rep says that an interview with Cosmo never even happened. She\'s saying it was all fabricated in an effort to gain readership. Now who\'s the famous actress who\'s got the singing voice of an angel but we\'ve never even heard it? It\'s Jennifer Aniston. According to her boyfriend, John Mayer, Aniston could become a successful recording artist. He goes on to say that she\'s shy about singing and that she only does it when no one is listening. That\'s it from the world of celeb gossip. I\'m Dana Ward at GetTheDaily.com, reminding you to always check back here for the latest news.
