Ryan Gosling Eva Mendes Pregnant Fight Over Rachel McAdams After Surprise Pregnancy: 'The Place Beyond the Pines' Couple 'Blindsided' By Baby Bump as Actor Still Cares For Ex-Girlfriend After Break Up

Although the world is anxiously awaiting the arrival of Eva Mendes and Ryan Gosling's baby, the couple was actually stunned to find out that the 40-year-old actress was pregnant.

According to RadarOnline.com, the "Lost River" star's pregnancy completely blindsided Gosling because their relationship had hit a rough patch just before his girlfriend shared the baby news.

A source revealed that when Eva Mendes discovered she was pregnant, "It was completely unplanned," adding, "Ryan was surprised, especially because they had broken up early last year, only to get back together."

The stars first started dating while filming "The Place Beyond the Pines" three years ago and have experienced the ups and downs of romance together. An insider said, "Their disagreements always come back to a central issue: Eva wants to marry Ryan, but so far, he has resisted."

However, the pregnant actress has moved into her boyfriend's bachelor pad. A source revealed, "The house is quite small, and only has two bedrooms," adding, "Eva has been looking for a bigger house to live in with Ryan once the baby is born."

As for now, the expecting starlet is pretty happy with life. A source told OK! Magazine, "She's been ready for motherhood for a while now and to be sharing this experience with Ryan is a dream come true for her!"

However, something that isn't a dream for Eva Mendes is that her boyfriend still cares for his ex-girlfriend Rachel McAdams.

In recent days, the source revealed, "Eva has been upset with Ryan over his reaction to comments Nick [Cassavetes, director of The Notebook], publicly made about Ryan feuding on set with Rachel McAdams."

Cassavetes recently claimed, "Maybe I'm not supposed to tell this story, but [Ryan and Rachel] really were not getting along one day on set . . .They had it out . . . .The rest of the film wasn't smooth sailing, but it was smoother sailing."

After the comments, the insider confessed, "Ryan called Nick and voiced his displeasure about him talking about his ex-girlfriend. Ryan is very protective of his privacy, and of the people around him. Rachel shouldn't have to be asked about it as she is out promoting a new movie."

The source claimed, "Rachel is definitely a source of ongoing tension between Ryan and Eva."
