Khloe Kardashian by Lamar Odom's bedside as he 'remains in a coma and his organs begin to fail'

Khloe Kardashian is by her ex Lamar Odom's bedside, as it's now reported his organs are beginning to fail.

The former NBA star is in a critical condition after being found unconscious at a brothel in Pahrump, Nevada.

According to TMZ, Lamar is still in a coma, and breathing "with the assistance of machines".

But the gossip website claims his heart is failin and he "is having serious problems with his kidneys and lungs".

E! News claims Khloe is "heartbroken", and the news has left her feeling "completely inconsolable and heartbroken".

The former NBA star was allegedly at the ranch for a number of days partying with girls and taking a herbal substitute for viagra, TMZ quoted sources as saying.

Hof reportedly told the site that 35-year-old Odom was found unconscious in a VIP suite with fluid streaming from his mouth.

Khloe and Lamar split in 2013 after four years of marriage.

The couple - who tied the knot after just a month of dating - had been separated for several months before the Kardashian beauty filed for divorce in December that year.

It was rumoured at the time that Odom was struggling with substance abuse issues and had cheated on his wife.
