Sydney Sweeney ain’t telling any pretty little lies with her lips in these pics … passionately kissing her man Scooter Braun during a romantic Central Park outing in NYC.

The actress and the music exec posted up on a rock sitting above a pond in the center of the Big Apple Tuesday, bundled up against the cold in thick clothes … but, the heat between them certainly seemed to keep them warm.

The pair later strolled through the park together … while a bodyguard followed behind them, in case anyone got any funny ideas of messing with the celebrity couple.

The two have grabbed dinner, partied together and even gone for a spooky night out at Universal Studios in L.A. … but, while hand-holding and flirtatious looks are par for the course, the two have managed to keep their lips to themselves — at least in public.

Also worth noting … Scooter and Sydney seem stronger than ever after her awkward run-in with her ex-fiancé, Jonathan Davino, over the weekend — hanging out multiple days in a row after going to NYC’s Comedy Cellar on Monday.
