Bruce & Kris Jenner Holding Hands At LAX -- I Love You Long Time

Bangkok really changed Bruce Jenner -- he returned to L.A. holding hands with his estranged wife today.

Kris Jenner was grinning for cameras as she and Bruce walked out of LAX with a tight grip on each other -- which seems odd for a bunch of reasons ... not the least of which being the fact they separated back in October.

Then again ... they're coming back from a Kardashian family trip to Thailand for their TV show -- so, as always ... hard to tell what's real and what's just for cameras.

Maybe Bruce just talked Thai real well.
