Lamar Odom is reportedly improving "little by little" in the hospital.

In the last several weeks, Odom has been making a decent amount of progress, Us Weekly reported.

"He gets better a little bit every day," a source told Us. "He took a few steps without the walker. It's very slow and he's supposed to go to the rehab any day now."

Odom, 36, was found unconscious in a Nevada brothel on October 13, and his toxicology report later revealed he had cocaine and herbal Viagra in his system. He's been seeking treatment and undergoing rehab ever since with wife Khloe Kardashian frequently at his side.

Kardashian, 31, and Odom were married for four years before the Keeping Up with the Kardashians star filed for divorce in December 2013 due to the former NBA player's alleged cheating affairs and drug abuse. However, the couple is still married because the divorce was never finalized, and Kardashian is therefore making Odom's medical decisions.

Just last month, Kardashian told Ellen DeGeneres on her talk show that Odom has no awareness of how he obtained a brain injury.

"We tell him that he had a brain injury, but we can't tell him how that brain injury was caused, because that will set him back," Kardashian explained. "He never asks why he's here. He doesn't ask. He's really confused a lot -- sometimes he knows who the president is and his birthday, and sometimes he thinks he's 26, and I say, 'I bet you wish you were 26, so do I!'"

Kardashian has been dating NBA star James Harden in the meantime while promoting her new book Strong Looks Better Naked.
