Khloé Kardashian ''feared'' Lamar Odom would end up in hospital.

The 'Keeping Up With The Kardashians' star was reportedly worried her estranged husband, who is currently being treated in hospital after a four-day drink and drug fuelled binge, would find himself in a difficult situation one day.

A source told PEOPLE magazine: ''This is exactly what she feared. Everyone is hoping that this will be a reality check for him and that he will make a change in his life and be the man he was created to be.''

Meanwhile, it was previously revealed that the 35-year-old basketball player may need to have a kidney transplant.

A source claimed the star is undergoing heavy dialysis, where a machine artificially removes waste from the body, a job the kidneys would usually do, as ''his kidneys are shot.''

However, his aunt JaNean Mercer is positive about his ''miraculous progress''.

In a statement, she shared: ''As Lamar begins a new chapter in his road to recovery, PLEASE continue to uplift him and the family in prayer. He continues to make miraculous progress, taking a few steps in Los Angeles. We couldn't be more overjoyed! We realize Lamar's continued improvement will not be easy, however his unrelenting strength and faith in GOD will pull him through. To everyone from across the nation and around the world who continued to send your love and prayers, we THANK YOU sincerely. (sic)''
