Nick Young -- Accepts D'Angelo's Apology ... 'But It'll Never Be the Same'

D'Angelo Russell has apologized to Nick Young in a face-to-face meeting earlier Wednesday -- and Nick accepted ... but things are still icy between the two.

As previously reported, Lakers honchos organized a sit-down between the players to hash things out over a video that Russell secretly shot of Young apparently admitting to cheating on his fiancee Iggy Azalea.

Sources close to Young tell us he accepted Russell's apology and the beef is squashed for now ... but as our source put it, "Everything is cool but it ain't gonna be the same."
