Lamar Odom was removed from a flight for being "wasted" and for vomiting in front of passengers.
The troubled basketball player - who suffered a near-fatal overdose in a Las Vegas brothel last October - reportedly downed beers and whisky in the Delta Lounge at Los Angeles International Airport while waiting for a late-night flight to New York on Monday.
After boarding the plane, he left his first class seat as the aircraft was about to take off, threw up in the galley and then vomited again in the bathroom.
Onlookers told TMZ that flight attendants "gently" escorted him from the plane and a cleaning crew came on board to deal with the mess, while flight attendants put Lamar's belongings in a plastic bag and removed them from the aircraft.
However, 10 minutes later, the 35-year-old sportsman returned to the plane, still with vomit on his clothes, and took his seat again.
However, moments later, he went back to the bathroom, using the heads of passengers to steady himself.
One passenger is said to have asked the cabin crew: "Don't you know his history? I don't want a dead body at 30,000 feet."
Lamar was again removed from the plane and the flight took off, arriving at its destination 40 minutes late.
It was recently claimed Lamar's estranged wife Khloe Kardashian has kicked him out of the lavish $25,000-a-month property she was renting for him near her Calabasas mansion while he recovered from an overdose last year after drug paraphernalia was discovered there.
However, an insider later insisted it was Odom's decision to move out.
A source said: "He has his own money. It was his choice not to [extend the lease] Lamar was ready to move on as well.
"They are divorcing and now that Lamar is doing better, he doesn't feel the need to live next door to Khloe. He has been staying with friends but is also looking for a new place."
