Ryan Gosling and Eva Mendes are two of the hottest and gorgeous couple in Hollywood, but it seems like there is trouble in paradise, as the duo have become subjects of another celebrity break up.

Gosling, 32, and Mendes, 39, are apparently still together but rumor has it that the couple's relationship is on the rocks, following their supposed brief break up six months ago, according to US Weekly.

In addition the possible source of the couple's problem might have been coming from Eva's too much "jealousy" and "insecurity."

A source close to "The Notebook" actor said, "He can be moody, and she's insecure. She sees a text from a mystery number and assumes he's talking to other girls... I wouldn't be surprised if they split for good soon."

Friends of the "The Place Beyond the Pines" actress have allegedly noticed a change in how the "Hitch" actress talks about her handsome partner.

"She shuts down anyone who brings up Ryan," a friend said.

"It's clear something is wrong."

However, a representative for Mendes denied to Us that the couple are having problems with their relationship.

The couple has been dating since September 2011 has had issues of splitting up mostly came from jealousy issues too.

It has been reported that Ryan almost went to a fistfight with a fashion photographer who previously worked with his ladylove Eva after the man greeted her, "Hey, Baby!" last March 29, when the couple was at the Bowery Hotel.

"Ryan completely flipped out, and it got heated," an insider told New York Post. "Ryan got in the guy's face and said, 'Who are you calling baby?' Eva had to jump in and calm everyone down before it came to fisticuffs. Ryan then made nice and shook the guy's hand," the eyewitness added. 

Furthermore, just last month, rumors circulated that the handsome duo is headed for a split because of Eva's unwillingness to commit to Ryan.

"The 39-year-old actress is not fulfilling 32-year-old Gosling's dreams of marriage and having kids right now," According to a report from Fox News Latino. "Ryan's friends know he is ready to settle down, 100 percent. Eva loves Ryan, but she's very nontraditional when it comes to what she wants. She's phobic about commitment. That's the root of the problem."
