Lady Gaga’s after-party for her Staples Center concert Monday night in Los Angeles turned into an impromptu photo shoot with lensman Terry Richardson. New York rockers the Dirty Pearls play the parties for the “Poker Face” singer’s North American tour. On Monday, Gaga spotted Richardson with camera in hand. Sources told us Gaga called him over and encouraged band members to pose for a series of fun candids. Richardson tweeted several of the pictures yesterday. Gaga and the Dirty Pearls lead singer, Tommy London, have been friends since her go-go dancing days at St. Jerome’s, where he worked as a manager alongside Gaga’s ex-boyfriend Luc Carl.
