DALLAS, May 14, 2010 / FW/ — As usual, Lady Gaga caused a paparazzi mayhem when she arrived at Carnegie Hall to attend and perform at the Rainforest Fund’s 21st Birthday Celebration Benefit Concert last night.

For her arrival, Lady Gaga wore a custom Calvin Klein Collection black needle punched silk taffeta seamless bustier dress.
