- The owner of the brothel Odom went to insists the ex-basketball star wasn't doing illicit drugs
- Odom was found unresponsive Tuesday after spending days at the legal brothel in Nevada
- After being unconscious for days, Odom said 'hi' to Khloe Kardashian, his estranged wife
Odom was hospitalized Tuesday after he was found unconscious at the Love Ranch, where he had been holed up since Saturday.
After being unresponsive for days, Odom said "hi" to his estranged wife, Khloe Kardashian, a source with knowledge of the situation said Friday.
It was unclear whether he remained conscious or how long he was awake.
Odom's college coach, Jim Harrick, told CNN's Anderson Cooper that Kardashian told him she reached down to Odom on Friday and told him she loved him. Odom blinked, he said.
"He's awake now," Harrick said. "So that's probably the most encouraging news we've had since it all started."
Odom is using a mask to breathe and has serious damage to his vital organs, his former mother-in-law, Kris Jenner, told "Access Hollywood."
'Tiny bit' of improvement
A source close to the situation told CNN on Friday the 35-year-old improved a "tiny bit" during his third night at Sunrise Hospital & Medical Center.
Odom "got a tiny bit better -- emphasis on tiny -- and he was responsive in the middle of the night for a moment," the source said.
Little is known about what left him unresponsive at the brothel in Crystal, where he was found Tuesday, three days after he checked in.
Most of the information has come from Dennis Hof, owner of the Love Ranch, where the former basketball player was found.
Hof told CNN's Michael Smerconish on Saturday that Odom was "in a good frame of mind" when he was transported to the brothel last weekend, adding that he ate and slept well once there.
"He picked a couple of girls, and he had the time of his life," Hof said.
Drugs and money
In three days at the brothel, Odom spent $75,000, which guaranteed two women would "take care of any of his needs," Hof earlier told CNN's sister network HLN.
Employees told 911 dispatchers that Odom used cocaine on Saturday -- his first day at the brothel -- though Hof insisted Saturday that this drug use happened when he was partying early that morning in Las Vegas but before he'd arrived at the Love Ranch.
"I'm going to protect my business, and I'm not going to let the world say that Lamar was doing a lot of drugs in my place," he told CNN's Smerconish, insisting his brothel has "zero tolerance" for illicit drugs. "Because it makes him look bad, and he wasn't doing that."
A woman said she also saw him take 10 herbal supplement tablets over three days.
The brothel's employees said when they found him, Odom was lying in bed on his side with a pinkish fluid coming from his mouth and nose.
Four teams, 14 seasons
Odom won two NBA championships as a forward for the Los Angeles Lakers.
He played for four teams during his 14 seasons in the NBA and won the Sixth Man of the Year Award during the 2010-11 season.
The Los Angeles Clippers drafted him in 1999, and he played for the team for four seasons before signing with the Miami Heat.
After one season in Miami, he was traded to the Lakers, and became a key part of their championship teams in 2009 and 2010.
He also played briefly for the Dallas Mavericks before returning to the Clippers for one season.
Odom and Khloe Kardashian got married in 2009 -- and filed for divorce four years later, citing irreconcilable differences.
In addition to appearing on "Keeping Up With the Kardashians," the couple had their own reality show, "Khloe & Lamar." It lasted for two seasons and 20 episodes.
The two signed divorce papers this year, but the divorce has not been finalized, a source told CNN.
Outside of basketball, Odom has continued making headlines, including for a drunken driving charge two years ago. He pleaded no contest and received three years' probation.
