The 29-year-old star is known to be close to her sisters Kim and Kourtney Kardashian and mother Kris Jenner. But she is said to have kept it quiet from them that she and NBA star Odom, who have been married for nearly four years, have been having issues, amid allegations he has a serious drug problem, reported Us magazine.
"Khloe did keep her marriage issues with Lamar a secret from her family for quite some time - no one knew," a source said.
Odom was spotted returning home 'looking gaunt' after reportedly going missing for six days after Khloe kicked him out because he did not want to go to rehab. His decision not to enter the facility is thought to be because basketball pre-season training camps are coming up soon, but following allegations the 33-year-old star has a drug problem, the Los Angeles Clippers are said to be refusing to re-sign him.
