Despite the happy photos of Eva Mendes and Ryan Gosling on set and red carpet premieres, insiders say that there has been trouble in paradise for the Hollywood couple.

Sources close to the couple say that Ryan's moods, Eva's insecurity, and the distance spent apart have taken a toll on their 2-year relationship. "She sees a text from a mystery number and assumes he's talking to girls," an insider close to Gosling said. "She shuts down anyone who brings Ryan up... It's clear something is wrong," the source added.

The last time the pair were reported together was in mid-September, when Mendes visited Gosling on the set of his upcoming directorial debut, How to Catch a Monster.

Referring to when the couple is rumored to have briefly split up six months ago, the insider affirmed, "I wouldn't be surprised if they split for good soon."
