After a huge scare, Lamar Odom reportedly woke up from coma in Sunrise Hospital and Medical Center to even say "Hi" to ex-wife Khloe Kardashian.

"Officials at Sunrise have not commented on the condition of Odom, whose medical decisions are being made by Kardashian, a source has told CNN. "CNN has reached out several times to the hospital for comment and no one has returned any of the calls."

However, Lamar Odom's condition "is still guarded," and it's not clear if he's still awake or lapsed back into coma or not.

Jim Harrick, the former high school basketball coach of Lamar Odom, told USA Today that his condition has indeed improved, according to Khloe Kardashian.

"She reached down and said 'you know I love you' and he kind of nodded," he said. "Three or four days after being scared to death and fearing the worst, that is a little hope, a little progress. She texted me that (information)."

"I think she is the best thing to have ever happened to him," Harrick said, talking about Khloe Kardashian.

Although she's already dating James Harden, the "KUWTK" star is still technically married to the former Los Angeles Lakers star since their divorce wasn't finalized yet.

Khloe Kardashian filed for divorce from Lamar Odom in December 2013 amid accusations of cheating and substance abuse. But both parties only signed the documents in July this year.

Lamar Odom was found by two prostitutes unconscious inside his room at a Las Vegas brothel on Tuesday. He later lapsed into a coma before reportedly waking up on Friday afternoon.

People magazine claimed to have talked to a source close to the family that Lamar Odom "opened his eyes" and "there has been some improvement" in his condition.

"Sources previously told PEOPLE on Thursday that the former NBA player was breathing with the help of a ventilator at Sunrise Hospital in Las Vegas," it said.
