FISHY DATE BACKGRID
Khloe Kardashian went out to grab a bite with her ex, Tristan Thompsonthis weekend -- without any kids around -- and while some might've thought the spark was back ... it ain't.
KK and Tristan were photographed walking out of Nobu Malibu Sunday -- where they were clearly dining together ... even though they appeared to stagger their exits, and ended up leaving in separate cars.
There were lots of other people with them, but none of their children -- which raised alarms among some who thought they were back together .
