Although Khloe Kardashian is trying to stay strong for her husband Lamar Odom, the reality TV star had to admit that even she's not bullet-proof.

"As much as I wish I were made of steel... I'm not," posted the "Keeping Up with the Kardashians" star on Twitter Sunday.

Yet in still, the 29-year-old wife assured the world that her husband's reported substance abuse and recent arrest on suspicion of driving under the influence won't break her completely.

"I'm pretty damn close to it though hehe," she added.

On Friday, her hubby was arrested on suspicion of driving under the influence (DUI) in California, TMZ reported.

The former LA Lakers player was busted by the California Highway Patrol while he was driving a white Mercedes SUV on freeway in the San Fernando Valley at 3:54 a.m. on Friday.  CHP officials say he was driving too slowly in a "serpentine manner" around 50 mph. Authorities attempted to pull him over, but he kept driving. When they eventually stopped him, Odom showed "objective signs of intoxication and was unable to perform field sobriety tests as explained and demonstrated."

As a result, he was arrested on suspicion of DUI and taken to jail in Van Nuys on $15,000 bail. . He refused all chemical tests, the Los Angeles Times reported.

According to People magazine, Odom was released from jail a few hours after his arrest, around 8:30 a.m. after posting bond. He has, however, lost his driver's license because he refused the chemical test, a decision that carries a one-year suspension.

He is scheduled to appear in court Sept. 27, according to the Los Angeles County Sheriff's Department report.

The arrest comes after news surfaced that the NBA free agent has allegedly been struggling with drug addiction. TMZ reported that he went missing for 72 hours and that substance abuse has also taken a toll on his marriage to Khloe Kardashian.

"It's a really hard time for Khloe. She's kept this secret for almost two years trying to save Lamar and their marriage," a source told People. "Lamar genuinely doesn't think he has a problem - it's all 'work hard then party hard' with him until it goes off the rails. They really do love each other. But she really feels that this problem is out of control, and she's hurt that he won't get help."
