Just two weeks after Lamar Odom was allegedly booted from a Delta Air Lines flight for being drunk and vomiting repeatedly, sources tell ET his loved ones fear for his health, adding that his friends and family attempted an intervention, but failed.
"Everyone is really worried for his safety right now," a source close to the former NBA pro revealed. "Lamar is not in a [good] place right now, we're really worried."
Part of those worries stem from Odom no longer receiving help from his estranged wife, Khloe Kardashian. When the 36-year-old troubled athlete was found unresponsive in a room at the Love Ranch brothel in Crystal, Nevada, last October, Kardashian remained by his side throughout his recovery.
"Thank God he had Khloe near his side in the fall," the source revealed. "If she wasn't there, God knows what could have happened to him."
"But now that Khloe is not in the picture anymore," the source continued, "there is no one there looking out for him with his best interests at heart. He won't listen to anyone. He has this attitude that if [his actions] haven't killed him already, [they] won't. It's sad and scary. I feel bad for his kids because they're really worried too. He really needs help, but he doesn't want to accept any of it."
Another source close to Kardashian tells ET that the two are "100 percent done" and are no longer on speaking terms. As previously reported, Kardashian, 32, filed for divorce from Odom for a second time on May 26.
"Things got dark," the source noted. "Khloe has done everything she can to help Lamar. It just wasn't enough."
Additional sources tell ET that Odom has been switching between homes in New York City. "He's been going out every night and doesn't return home until 1 p.m.," the source added.
ET has reached out to Odom's family rep for comment.
Earlier this month, Odom was spotted at a strip club in the Big Apple just one night after the alleged airplane incident. Hear more on that outing in the video below.
