Selena Gomez and The Weeknd aren't gonna be getting cute together in public anymore -- 'cause they've broken up ... TMZ has learned.

Sources close to the situation tell us Selena and Abel split recently -- this after publicly dating for a little more than 10 months. We broke the story ... the couple was first seen making out in public back in January.

It's been a fun ride with these two -- we've seen them put on the ultimate PDA in just about every damn setting you could imagine ... from a Dave & Buster's date to a tour of the Galleria dell'Accademia in Italy, plus hand-holding at Coachella ... and everything else in between.
