Khloe and her husband Lamar Odom have been hit by numerous reports that their marriage is on the rocks, so her decision to leave her ring at home while attending a big event is significant.
When rumours of a split first surfaced back in the summer, Khloe made a deliberate point of wearing her giant diamond sparkler, as reported on Reveal.co.uk.
Last night, however, her left hand was bare as she walked the red carpet at the Hollywood Reporter's Women In Entertainment Breakfast in Los Angeles.
Khloe, 29, was wearing a stunning white wrap dress and she carried a gold studded clutch - making her missing ring all the more obvious.
The US reality star was first spotted without her ring on 23 November, after returning from a promotional trip in Australia.
She reportedly spent Thanksgiving apart from 34-year-old Lamar, who was rocked by reports of drug use in August.
According to American magazine Us Weekly, the couple are heading for a very permanent split - very imminently.
"She's filing for divorce very soon," the insider was quoted saying. Khloe has not commented on the claim.
Earlier this week, Khloe and Lamar both attended a Jay-Z concert but apparently they arrived separately and did not interact.
