Lamar Odom in a coma, has ’50-50’ shot of surviving......

Two-time NBA champ Lamar Odom, a star on the court and basic cable, had only a 50-50 chance of surviving after a three-day drug binge left the helpless hoopster in a coma.

The Queens kid who married a Kardashian remained unconscious Wednesday, a day after he was found facedown and nonresponsive inside a Nevada brothel, with a ventilator now keeping the 6-foot-10 player alive, officials said.

“Please don’t go,” read a terse and touching tweet sent Wednesday morning from Odom’s 19-year-old sister-in-law Kendall Jenner.

His daughter Destiny also tweeted her affection for her father.

“Soon I’ll be by your side and I’ll never let go,” wrote the devastated 17-year-old. “I love you daddy. Please don’t leave us.”

The 14-year NBA veteran was foaming at the mouth and apparently gagging on his own mucus after ingesting “every drug imaginable,” a Sunrise Hospital & Medical Center source told E! 

Odom was drinking cognac and had been downing herbal sexual enhancement pills called Reload for the length of his stay, sources said.

“We were advised that they were obtained at the establishment,” police said of the supplements.

The pills are available for sale at the ranch, but Odom also could have bought them elsewhere, said Dennis Hof, the renowned owner of the ranch.

He told one of the hookers “that on Saturday prior to arriving here that he had used a small amount of cocaine,” said Richard Hunter, a spokesman for the ranch.

The cause of his collapse was not officially confirmed, although investigators tested Odom’s blood for drugs and alcohol Wednesday.

Odom, 35, looked more Lenny Bruce than Los Angeles Laker upon arrival at the Las Vegas hospital, with cocaine in his system and needle marks on one of his arms, according to TMZ.com.

He arrived at the ranch in a car dispatched Saturday from the ranch to his Las Vegas residence.

Sources told the website that Odom’s chances of survival were “50-50.” Other reports indicated his organs were failing, and doctors were concerned about possible brain damage.

A star-studded circle of family and friends stood vigil alongside the unconscious athlete’s bed — estranged wife Khloé Kardashian, her sister Kim, former Los Angeles Lakers teammate Kobe Bryant and the Rev. Jesse Jackson.

“She has been with him, by his side, since 8 p.m. last night,” a source told the Daily News of Kardashian. “Her mom and Kim are there as well. She will not leave his side.”

Khloé, who has been making medical decisions for her estranged husband, reportedly arranged to have Odom’s two children from a previous relationship fly in from New York.
