Sydney Sweeney‘s not hearing wedding bells in her near future … ’cause she’s pushing back her nuptials, TMZ has learned.

Sources with direct knowledge tell TMZ … the actress was supposed to get married in May, but the wedding’s now on hiatus — and, it’s not totally clear why.

We reached out to people in the know … and, they confirmed to us the wedding was being pushed back because of the couple’s busy schedule.

They’ve been together ever since … surviving rumors that Glen Powell and Sydney were head over heels for one another on the set of “Anyone But You” — claims SS vehemently denied. Davino and Sydney were last spotted out together last month.

Worth noting … Sydney consistently seems too busy to plan this wedding — ’cause she told Entertainment Tonight back in December 2023 that she’s “so busy working! I’m a workaholic and I love it, I love it.”

Unclear what exactly is making Sydney push back the wedding … but, we do know she’s got a couple movies coming up including a Kim Novak/Sammy Davis Jr. biopic — so she could be shooting something soon.
