Sydney Sweeney may have been spotted rubbing shoulders with single A-listers like Orlando Bloom and Tom Brady during Jeff Bezos and Lauren Sanchez‘s wedding weekend … but TMZ has learned she’s not dating anyone.

Sources with direct knowledge tell TMZ … the actress is very much single despite the swirling speculation after she was seen spending time on a stroll through the streets of Venice, Italy with both Bloom and Brady.

Our sources say she’s not interested in dating anyone after calling off her engagement to fiancé Jonathan Davino. We broke the story … the former couple separated in January.

We broke the story … Brady “danced with everyone” — including Sydney and Brooks Nader — during the wedding reception Friday night, but we’re told no one hooked up.
