Ya play well, ya eat well ... that seems to be the motto with the New York Knicks -- 'cause Kristaps Porzingis just got invited to dinner at Carmelo Anthony's house.
Melo's actress wife LaLa -- star of "Unforgettable" -- was out in NYC when she told us Porzingis has been playing so well, he's "earned a spot at our dinner table."
FYI -- Porzingis has been playing out of his mind this season ... racking up 9 double-doubles in 19 games ... as a 20-year-old rookie.
In fact, the Latvian sensation is so impressive, Lala says Melo has even made the effort to learn some of Kristaps' native language. Interesting, since Kristaps once told TMZ Sports he didn't think ANYONE would wanna learn Latvian!
Funny how things change ...
