The 43-year-old was spotted wearing a large diamond on the ring finger of her left hand as she vacationed in Santa Fe, New Mexico, with her fiancé over the weekend. The actress has been in nearby Albuquerque shooting scenes for her upcoming comedy "We're the Millers."

So what was the reason for the delay in debuting the sparkler? It's unclear whether Aniston only recently got the ring or if her main squeeze gave it to her back when he popped the question on August 10, which also happened to be his 41st birthday. Perhaps she just held off on sporting it since she's been working on set so much? In the film, she plays a woman hired by a drug smuggler to pretend to be his wife, and thus, spends many of her scenes wearing a simple gold wedding band. Some speculated that the band might actually belong to Aniston, but most of us were patiently waiting for her to debut some big bling.

And now that she finally has, no one within miles can miss it!
