Khloe Kardashian hinted via Twitter her marital problems with professional basketball player Lamar Odom are taking a toll on the "Keeping Up with the Kardashians" star.
"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.
