LAS VEGAS — Lamar Odom didn’t last long at the glittering intersection of championship success and Hollywood celebrity.

Cut loose by his beloved Los Angeles Lakers, followed everywhere by reality television crews, the humble kid from Queens who married into the Kardashian clan saw his life spiral out of control, and so did everyone else.

Khloe Kardashian tried to hide his addictions, then told the world she couldn’t save him. The two-time NBA champion landed on Skid Row, a regular tabloid target.

Then he seemed to drop out altogether before he was found unresponsive in a brothel and hospitalized, bringing his estranged wife, his former teammates and the world’s attention back to his side Wednesday.

Hospital authorities would not comment on the condition of the 35-year-old former NBA forward, but the Rev. Jesse Jackson was among his visitors Wednesday. Jackson said Odom was on life support and improving.

“Apparently from what the doctor said, he was much better off today than yesterday. He at least has some responsiveness now,” Jackson said. “He’s got tubes in him now, but we felt inspired by his presence.”
