Khloe Kardashian says she isn't "made of steel."

The reality TV star is trying to cope with her relationship troubles and her husband Lamar Odom's recent DUI arrest - and she has taken to her Twitter account to hint it's proving difficult to stay strong: "As much as I wish I were made of steel ... I'm not ... I'm pretty damn close to it though hehe."

Khloe, 29, previously left a cryptic, but optimistic, message to her followers on the social networking site, which she has since deleted. "Smile and no one will notice," she wrote.

According to recent reports, the couple were reunited at their California mansion, but the star's family are pushing her to end their romance because of his arrest and alleged drug use. Lamar was stopped by the California Highway Patrol on Friday and released after posting $15,000 bail. "Kris wants Khloe to get her prenup money, plus the penalty for cheating. Kim, Kourtney [Khloe's sisters] and Kris want her to dump him. You can't live with a drug addict," a source said.
