Eva Mendes and Ryan Gosling: Inside Their Whirlwind Relationship

1205C0verAAA.jpgGoing from Ryan Gosling's co-star in The Place Beyond the Pines to the actor's serious girlfriend in a matter of months, Eva Mendes has become the envy of every girl by snagging Hollywood's most eligible bachelor!

"Ryan is obsessed -- he wants to see Eva all the time," a friend tells Life & Style. "I don't know what it is about her, but he's into Eva hook, line and sinker!"

In the new issue of Life & Style -- on newsstands now -- the passionate relationship is chronicled from the couple's instant chemistry on set to late-night make out sessions and exotic trips -- Ryan swept Eva off her feet in Paris over Thanksgiving and introduced her to his mom, Donna, on New Year's Day. And now Ryan's even thinking marriage!

"Even when the cameras weren't rolling, they were really affectionate with each other," Nicole Sykes, who was an extra on the Altamont, N.Y., set of The Place Beyond the Pines on Aug. 19, tells Life & Style about the couple's instant connection. "Eva was kissing Ryan's head and cuddling with him while they sat on the ground. You could tell that she really liked him."

Friends say Ryan is head over heels. "Eva's wildly passionate and impulsive. He thinks of her as the female version of himself," a friend tells Life & Style. But the friend adds that his protective mom and close-knit family are cautioning Ryan to put the brakes on his whirlwind affair.

"Ryan's family is worried; Eva's so LA," shares the friend. "She's so into the business and not a super-warm person." And while Ryan has hopes for marriage in his future, by Eva's own admission, Ryan may be setting himself up for disappointment with her. "I don't believe in the institution of marriage," Eva has said.
