Great news from gagadaily.com ! Lady Gaga had some really cool celebs attended her performance in NYC this past Saturday. Press spotted Alicia Keys, Tyra Banks and Janet Jackson (what an honor to have Janet at her concert) at Lady Gaga’s concert. Among those A listers was none other than the wonderful Madonna! With so much comparison between the two, I bet Madonna had a great time watching the “younger” version of herself perform and rip the stage!Were so proud of Gaga and its awesome to see other artist supporting her!
