Rachel McAdams/Ryan Gosling, “The Notebook”
On-screen: They sizzled together as forbidden lovers. Forced apart as teenagers, their characters reunite years later, as the rich girl finds herself unable to forget the passionate poor boy.
Off-screen: Passions reportedly flared up between Gosling and McAdams during the filming of the movie, but their romance eventually fizzled. Today, Gosling is still on the market, after being romantically linked to Sandra Bullock. McAdams is currently dating “Glory Road” actor Josh Lucas; their romance became public when they were spotted together at inauguration parties in Washington this past January.
