Khloe Kardashian seemingly isn't going to keep her marital woes quiet for much longer. The Keeping Up With the Kardashians star opened up for the second time on Twitter since husband Lamar Odom's DUI arrest on Aug. 30, and hints that she's trying to be as strong as possible amid her marriage woes.

"As much as I wish I were made of steel...I'm not," the 29-year-old wrote. The reality star seemed to imply that she's dealing with her very public marriage problems and Odom's substance abuse as best as she can. She added: "I'm pretty damn close to it though hehe." 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. The professional athlete was later spotted still wearing his engagement ring while buying intense, brooding DVDs (like Passion of the Christ and The Road) at Blockbuster in Calabasas, Calif., while Kardashian looked glum trying to cover up from photographers in an oversized black hoodie on her trip back to their home.

Meanwhile, the rest of the Kardashian clan has been keeping tight-lipped on the situation. Older sister Kourtney Kardashian celebrated Labor Day early by hosting a bash at Hyde Bellagio in Las Vegas, Nevada Sunday. First-time mom Kim Kardashian has been active on social media, but has yet to mention anything about her sister's ordeal.
