On July 29, a bruised Hilton showed up at Los Angeles International Airport with her sister Nicky. Ex-boyfriend Nick Carter immediately went on the defensive after rumors spread that he caused her bruises. "I didn't touch her," he told PEOPLE. "I'm not that kind of guy." Hilton never revealed how she received the mysterious injuries. "I'm doing okay. I'm just so happy to be single right now," she said at the time.
