Ryan Gosling may be the object of many fans' affections, but when it comes to his own personal life, he shares that he's only had two true loves: Sandra Bullock and Rachel McAdams .

"I had two of the greatest girlfriend of all time. I haven't met anybody who could top them," the 30-year-old star told UK-based newspaper The Times , about Bullock (who he dated from 2002-2003) and McAdams (who he dated from 2004-2008).

The Drive actor claims that Hollywood is to blame for the end of his relationships.

"Showbusiness is the bad guy. When both people are in show business it's too much showbusiness. It takes all of the light, so nothing else can grow," the actor, who has also been tied to actresses Blake Lively , Olivia Wilde and Kat Dennings , said.

But it seems one possible relationship seed has been planted: Gosling, 30, was spotted on a private tour of Disneyland , hand-in-hand with Eva Mendes , 37. The pair walked through the magical theme park, stealing kisses from each other and showing major PDA.

Gosling did confirm to The Times that he is in one committed relationship: film. "I'm giving as much to it as a marriage," he said. I'd like to be making babies but I'm not, so I'm making movies. When someone comes along I don't think I'll be able to do both and I'm fine with that. I'll make movies until I make babies. I have no idea when the handover will happen."
