Ryan Gosling couldn’t help but gush about his girlfriend and mother of his daughter Esmeralda, Eva Mendes, in a rare interview that he talked about his personal life.

The actor, who hosted Saturday Night Live this past weekend, said he’s sure that Mendes, 41, is the only one for him.

"I know that I'm with the person I'm supposed to be with,” he told Hello! magazine.

He was even asked what quality he has to see in the woman he’s with and he made it clear that he’s satisfied with everything Mendes brings to the table.

“That she's Eva Mendes,” he said. “There's nothing else I'm looking for."

Gosling, 35, went on to share his excitement for this Christmas with their 1-year-old daughter. "This will be our first Christmas where [Esmeralda] is sort of taking it all in, so that's exciting," he said.

Back in March, the new mom said she enjoyed "sleepless nights" up with their daughter because she views it as "bonding time."
