Lebron James believes the SHALACKING that the Lakers put on the Cleveland Cavaliers last night was an act of "Karma" ... for all the anti-LeBron trash talk he endured back when he left the squad.
In case you missed it, the Lake Show beat LeBron's old team by 55 POINTS last night ... and LeBron watched the whole thing at Boa Steakhouse in West Hollywood.
During the beatdown, Lebron tweeted, "Crazy. Karma is a b****.. Gets you every time. Its not good to wish bad on anybody. God sees everything!"
Spies inside the restaurant tell us LeBron was hanging with a group of people inside the steak joint ... including one massive bodyguard.
