Last month Sydney ditched her engagement ring amid rumours of a fling with Top Gun actor Glen Powell.
The White Lotus star went without the £120,000 band during an event in New York.
She is said to have grown close to Glen, 34, while shooting rom-com Anyone But You this year, and looked cosy with him in Las Vegas last week.
However, Sydney was spotted out with her partner of five years, Jonathan Davino, 39, in New York.
