Who knew Lady GaGa was a baseball fan? Actually I am not sure she is, but she was at the NY Mets game last night and was sitting down by the field but eventually grew tired of photographers taking her picture and just being amongst the regular, lovable people you will find at any NY sporting event. One Mets fan took the picture above and posted it to his Twitter. Good job Jimmie Kassab. So, she made the trek up to Jerry Seinfeld's box and when the photographers and people kept taking pictures, she decided to flip them the bird. She was then lustily booed as only NY sports fans can do.Of course they also might have been disturbed that she was only wearing the same outfit she was wearing in her Telephone video. Oh, and a bandanna.
