Khloe Kardashian axes TV taping

Reality TV star Khloe Kardashian canceled a recent taping of her talk show Kocktails With Khloe due to illness.

The Keeping Up With the Kardashians star pulled out of a shoot on Thursday (31Mar16), claiming she was unwell, but sources tell TMZ.com her sickness was caused by her concern for estranged husband Lamar Odom.

The former Los Angeles Lakers basketball player, who has had a well-publicized battle with addiction, sparked fresh fears for his health last weekend (26-27Mar16) after he was spotted ordering a number of drinks at the Johnny O'Brien Irish pub in Sherman Oaks, California, before joining the Kardashians for an Easter Sunday church service.

Khloe is reportedly worried Lamar's drinking may lead to a drug relapse, months after he was found unconscious from an overdose in a Nevada brothel in October (15). He also suffered a series of strokes and spent months recovering in hospital, followed by physiotherapy sessions to help him get fully back on his feet.

Now his former spouse is said to be urging Lamar to check into a substance abuse program to conquer his addiction issues once and for all - but he is refusing and the personal drama has allegedly left her an emotional wreck, according to TMZ.

Insiders claim the pair became embroiled in a huge fight earlier this week (begs28Mar16), leaving Khloe feeling "physically ill" and prompting her to halt filming on her hit late night show.

"Lamar is happy to go to physical rehab, but refuses to deal with his drug demons," a source previously told the publication. "Khloe's even suggested an outpatient program, but Lamar remains defiant. Khloe's telling friends and family there will come a point when 'she has to stop trying' to save Lamar."

Khloe filed for divorce from Lamar in December, 2013, but withdrew her court papers in the weeks following his health emergency last year (15) so she could make emergency medical decisions on his behalf.

The couple wed in 2009 after a whirlwind romance.
