Gerard Butler wasted no time in chatting up the ladies at Fashion Week, working his famous charm on Danish singer Oh Land as they sat front-row at the Diesel Black Gold show yesterday. A spy reports Butler took a shine to the beautiful blond ex-model, formerly Nanna Oland Fabricius, at Pier 94 and, “began chatting and invited her to the screening of his movie, ‘Machine Gun Preacher,’ but didn’t realize her boyfriend was standing at the back of the room.” A friend of the singer said, “Gerard was charming but she is totally in love with her boyfriend, artist Eske Kath.” Over at Lincoln Center, two worlds collided when Beyoncé and Kim Kardashian arrived at the same time with their security entourages. One spy told us, “There was a huge commotion.” Slipping in unnoticed, and without security, between the divas was former Secretary of State Madeleine Albright, who also sat front-row at Vera Wang with Kardashian. Albright looked fashionable in her knee-length leather skirt. She told us, “I wore the leather skirt because I thought it was hip.”
