Khloe Kardashian tweets after Lamar Odom's DUI arrest TV personality Khloe Kardashian arrives for Nickelodeon's 26th annual Kids' Choice Awards at the Galen Center in Los Angeles on March 23, 2013. 2 (UPI) -- U.S. reality TV star Khloe Kardashian hinted via Twitter her marital problems with professional basketball player Lamar Odom are taking their toll on her. Odom was arrested for allegedly driving under the influence of drugs and alcohol last week, shortly after returning home following a brief separation from Kardashian, his wife of nearly four years. "As much as I wish I were made of steel...I'm not," Kardashian tweeted during the weekend. I'm pretty damn close to it though hehe. She previously posted a message on Twitter saying "smile and no one will notice." Other than the vague online postings, Kardashian has not publicly spoken about her recent woes, which reportedly stem from Odom's alleged substance-abuse issues. UsMagazine.com said the couple have not been photographed since arriving home in separate cars Friday following Odom's arrest.
