Lamar Odom is seen just days before his hospitalization.
We're now getting a more detailed look at Lamar Odom's four-day stay at the Love Ranch in Crystal, Nevada.
In surveillance video obtained by ET, the 35-year-old basketball star is seen at the brothel surrounded by and talking with women, as he walks through the halls with them. An employee tells ET that Odom ate a steak dinner on Saturday, and was "sweet."
Odom arrived by himself at the legal brothel late Saturday night. Love Ranch owner Dennis Hof previously told ET the former NBA player "was in a great mood" and paid $75,000 for his stay. According to an itemized receipt obtained by ET, Odom was charged by four women on Saturday, and racked up a bar tab of $1,036 for the day. He also paid $100 for limo transportation.

"It was Lamar's idea. He said, 'I'll give you two girls for $75,000 the entire time I'm there -- minimum of four days and max of five days," Hof said. "We picked him up at his place in Las Vegas, brought him out there, great mood, ready to have a good time. He just wanted a little peace and quiet and get away from the pressures of his life."
"He did get a phone call on Sunday that upset him a little bit, but I don't know what that was about," he added. "But after that, he regrouped, and he was eating good, sleeping good and just having a good time."
"He was so sweet," another Love Ranch employee tells ET. "This all turned into an absolute tragedy."
Hof confirmed to ET that the two women Odom handpicked to spend time with at the brothel -- Ryder Cherry and Monica Monroe -- were also the women who found the athlete unconscious in his suite.
"We called 911, my staff did. They said 'roll him on his left side' and he started throwing up a lot but he was breathing. Then the ambulance and the police came and took him to the [hospital]," Hoff said. "They said he was in bad shape and they thought he might not make it."
According to the 911 calls released by Nye County Sheriff’s Office on Wednesday, Odom had used cocaine on Saturday. When asked about known drug use, the 911 caller told the dispatchers that Odom had also taken an "enhancement" supplement, consistent with Hof’s claims that Odom had taken an herbal Viagra substitute during his stay. Detective Michael Eisenloffel told reporters that he had been advised that Odom had obtained the supplement at the Love Ranch.
No one is currently checked into the Love Ranch, and no one has been since Odom's hospitalization on Tuesday, a source tells ET.
On Wednesday, Odom was placed into a medically induced coma and on dialysis, after starting to experience kidney failure. He remains in critical condition.

"Thanks for your outpouring of prayers and support for our dad," Destiny and Lamar Odom Jr. said in the statement to ET. "We are here with our family and friends. We appreciate everyone respecting our privacy at this time. We ask for your continued prayers."
