The on-again-off-again couple were snapped arriving at LAX on Sunday (8 March) following a brief holiday in Key West, Florida with friends.
Khloe and French didn't seem to be hiding the fact they were together, strolling alongside each other through the terminal.
They've enjoyed an on-off relationship since last year.
Khloe and French were first linked in April 2014, with sources saying they were casually dating and enjoying hanging out with each other. They hooked up after Khloe filed for divorce from husband Lamar Odom.
They took things public at Khloe's 30th birthday celebrations, with French appearing alongside Khloe and her famous family in a string of Instagram snaps from the bash.
French even appeared on Kourtney & Khloe Take The Hamptons!
However, it appeared they'd split at the end of the year.
Are they back on now?! Or are they just friends?! As neither Khloe nor French have said anything we guess we'll file this under 'don't know' for now!
Meanwhile, while Khloe and French are enjoying themselves over in the US, a fair few of Khloe's family have been making headlines over in France at Paris Fashion Week.
Older sister Kim Kardashian has been stealing the show thanks to her mega-blonde new hairdo, while younger sister Kendall Jenner is walking the runways. Mum Kris Jenner, niece North West and brother-in-law Kanye West are also at PFW.
