Rumors are flying that Ryan Gosling and Eva Mendes could be hiding a secret engagement from fans after the actress and fashion designer has continued to sport an emerald ring on her right hand for months.

Are Ryan Gosling & Eva Mendes Having Relationship Trouble? 

Mendes has been sporting the large stone on the ring finger of her right hand for about two months, and it has appeared in several images on her Instagram account-leading to speculation from The Daily Mail that it is actually an engagement ring from Gosling, but that the pair are trying to keep it a secret with Mendes intentionally wearing it on her right hand instead of the left.

The first time it appeared in an image on Mendes' account was in July, when she posted a photo of herself working on her upcoming winter collection for New York and Company, where she sits on the floor on her knees, with the ring clearly visible on her right hand.

It was also present during her appearance to promote a new line of cosmetics from Estee Lauder.

The ring has also been in a recent image where she promoted a new design for one of her dresses.

Mendes' reps have allegedly refused to comment on her personal life, meaning the story behind the ring isn't being confirmed, though others have already reported that it is likely not an engagement ring at all, and is just a piece of jewelry the actress loves-with E! News speculating it could be a regular present from Gosling, and not an engagement ring.

However, the couple is known for being notoriously private about their personal life. During Mendes' pregnancy in 2014 she managed to escape all possible photos of a baby bump and was able to keep the pregnancy news a secret for seven months. Since their daughter, Esmeralda, was born in September of last year, the pair have successfully kept her from being photographed even once.
