The handsome Australian pair was spotted wearing matching rings on those fingers on Monday, Jan. 20, in Sydney.
The model arrived for a photo shoot for Australian retailer Cotton On—she is the face of the brand—sporting a simple gold band on her left hand. The Avatar actor later arrived to visit his ladylove on set with a similar piece of jewelry on his ring finger. The duo appeared to be in good spirits and left together.
A representative for Bingle confirmed to Who magazine several weeks ago that the blond beauty "is not or has not married Sam Worthington in a beach ceremony," but that was before this recent sighting with the telling jewelry.
Bingle most recently shared a behind-the-scenes glimpse into a photo session with Cotton On on Wednesday, Jan. 22: a faceless snapshot showcasing her fit body in a very skimpy bikini.
But alas, no snapshots with her possible fiancé or husband revealing any more clues.
Worthington and Bingle were first rumored to be an item back in September when they attended the Cotton On Foundation's Global Citizen Concert together, and since then they've been photographed kissing and holding hands.
