No, this is not a picture from last season ...
LeBron James and Kevin Love were in the gym together Thursday morning -- smiling like two guys who don't hate each other's guts.
Of course, Bron just ditched Kev and the Cavs for L.A. -- and according to multiple reports, he didn't even text Love before going public with his decision.
And, don't forget ... LBJ and Love's 4 years in Cleveland together weren't exactly drama free -- remember Bron admitted he called out Kevin on Twitter a few years ago?
But, that's all water under the bridge ... because Kevin posted this reunion pic in a Vegas gym ... and captioned it, "Thursday morning work."
Also, LBJ publicly congratulated Love on his 4-year, $120 mil. extension with the Wine and Gold earlier this week ... so, maybe better friends than coworkers?
