In a blockbuster world exclusive, Breaking Celebrity News has obtained surveillance video from the Love Ranch brothel that shows Lamar Odom partying and popping pills in the final hours before his tragic hospitalization.

The disturbing footage taken inside the Crystal, Nevada, Love Ranch on Saturday, October 10, shows the former NBA great in what could have been his last drug and booze bender.

It has been seized by cops investigating the incident, Breaking Celebrity News has learned.

As this site reported, Odom arrived at the brothel on Saturday afternoon, and quickly made his way to the on-site bar.

In the footage obtained by The National ENQUIRER and Breaking Celebrity News as part of a joint investigation, the drug-addled 35-year-old can be seen sitting slumped dejectedly in the background around 5:30 p.m., as a prostitute in a bikini top and thong underwear prepares regular-sized drinks and shots.

Brothel owner Dennis Hof, the author of The Art of the Pimp: One Man's Search For Love, Sex & Money, confirmed that former Lakers star Odom drank from a bottle of cognac while on site.

The Nye County Sheriff's Department also revealed that Odom used both cocaine and herbal Viagra in the hours before his overdose, and the video appears to show him popping the fateful pills.

In one scene, Odom is shown putting his left hand into his pocket and retrieving a baggie. He tips the baggie into his hand and pops a pill into his mouth.

Not long after, employees of the ranch would find Odom unconscious in his VIP suite, covered in what the sheriff called "a white substance" and blood.

He is currently in critical condition at Sunrise Hospital in Las Vegas, where the prognosis is grim: Insiders told Breaking Celebrity News on Thursday he is clinically brain dead.
