Former NBA player Lamar Odom was found unresponsive by two girls at the Love Ranch South brothel in Nevada.
After alerting staff that the Keeping Up With The Kardashians star was unconscious, they called 911, who instructed staff to “roll him on his left side.”
Brothel owner Dennis Hof, speaking to CNN, said that "a bunch of ugly stuff came out of him."
Lamar married Khloe after a whirlwind marriage in 2009.
After going through some relationship difficulties, including rumours of the Laker star’s alleged drug abuse and affairs, the couple filed for divorce in 2013.
They finalised the divorce earlier this year.
Despite going separate ways, Khloe Kardashian has said she will always love him.
"I will never, ever not love Lamar," she told E!.
"I was so obsessed with him in a healthy way. He was my husband, and I still wish he was."
According to the show, the couple still regularly speak on the phone.
Reports suggest Khloe is currently by Lamar’s bedside in hospital.
