Khloe Kardashian feels "helpless" after her estranged husband Lamar Odom was spotted at a bar in Los Angeles over the weekend just months after his near-fatal overdose.

The 'Keeping Up With the Kardashians' star has hinted she's fed up of trying to defend her former spouse after photographs surfaced this morning (29.03.16) of the basketball player - who almost died in October following a drugs and alcohol binge - downing drinks with two friends at the Johnny O'Brien pub in Sherman Oaks, California, in the early hours of Easter Sunday morning (27.03.16).

Taking to her Twitter account just hours after the shots, obtained by TMZ.com, were splashed online, Khloe wrote without further explanation: "I hate this feeling.... Helpless."

And it seems Khloe, who vowed to stick by her former lover throughout his recovery, isn't the only one concerned for his health as his friends are worried his recent boozy night on the town could be the start of something more sinister.

A source told the publication: "We all are really, really sad he's decided to do this."

It's believed Lamar, 36, downed three Rémy Martin - the same champagne cognac he drunk the night he collapsed last year - before leaving the club at around 1am.

Just hours later, the sportsman got up bright and early to attend church with Khloe, 31, whom he split from in 2013 following four years of marriage, and her famous family.

Meanwhile, Lamar's behaviour over the weekend no doubt came as a blow to his nearest and dearest as he's been showing signs of a positive recovery over the past few months after he was found unconscious at a brothel in Nevada five months ago following a wild drinking session.
