TMZ is reporting that Khloe Kardashian's estranged husband is fighting for his life after being found unconscious at a Nevada Brothel.

According to the report, Lamar Odom has been partying at Dennis Hof's "Loveranch" for several days before one of the women he'd been partying with found him unresponsive in his VIP suite Tuesday afternoon.

When a manager rolled the basketball star onto his side they saw a mucus-type liquid coming out of his nose and mouth before calling 911.  At this time, it seems like he's been intubated and is being transferred from the Pahrump, NV hospital to Las Vegas for more extensive care.

Odom had been partying at the ranch without an entourage or friends and was supposedly taking an herbal substitute for Viagra since checking into the ranch on Saturday.  He's alone at the hospital and it's unclear if his estranged wife has tried to make contact with his care takers.
