Keith Urban was not in a fighting mood during his first performance since news of his split from Nicole Kidman broke. The country singer, 57, notably left a love song inspired by his estranged wife off his setlist when he performed on Thursday, October 2, at Giant Center in Hershey, Pennsylvania. Urban removed "The Fighter," a collaboration with Carrie Underwood, from his concert, which Us Weekly attended, after word got out earlier this week that he and Kidman, 58, had called it quits.
