Khloé Kardashian Odom opened up for the second time on Twitter since husband Lamar Odom's DUI arrest, Us Weekly reports. "As much as I wish I were made of steel . . . I'm not," the "Keeping Up With the Kardashians" star wrote. She previously tweeted to "smile and no one will notice," but has since taken that comment down. Since arriving home in two separate cars on Friday following the arrest, the spouses of nearly four years haven't been photographed together.
