WEDDING bells are finally set to ring for EVA MENDES after RYAN GOSLING won a hard-fought campaign to get the marriage-shy sexpot to settle down and start a family.

A year into their romance, the 31-year-old actor has begun shopping for an engagement ring for his 38-year-old ladylove, who has long insisted she’s not the marrying kind, say insiders.

“Ryan is head over heels in LOVE with Eva, and he wants to have a life with her – including children,” divulged a friend.

Even though the handsome “Drive” star has long been ranked as one of Hollywood’s biggest catches, Eva wanted to maintain her independence.

The actress, who split with Peruvian film­maker George Gargurevich in 2010 after dating eight years, has called marriage an “archaic kind of thing.”

But now the “Last Night” beauty hears her biological clock ticking. She’s long yearned to start a family and even investigated adoption two years ago, disclosed an insider.

“Ryan wants children too, but also believes in marriage and youngsters growing up knowing mommy and daddy are committed to each other,” said the insider.

“It’s something Eva has balked at in the past, but Ryan has a charming way of helping her see a different kind of future. She’s getting on board with the idea of marriage.”

Gosling, who’s romanced Rachel McAdams, Blake Lively, Sandra Bull­ock and Olivia Wilde, “is now confident that when he pops the question, Eva will say yes,” added the friend.

“They are likely to announce their engagement in October, followed by a summer wedding.”
