#10: Rachel McAdams and Ryan Gosling
Here’s something for all the Notebook fans: While Ryan Gosling and Rachel McAdams sizzled with chemistry on screen, their off-screen relationship started on a much frostier note. Gosling reportedly couldn’t stand working with McAdams during the early stages of filming and even went so far as to suggest she be replaced.
He was so frustrated that he initially refused to kiss her. However, something shifted during production, as the two eventually began a real-life relationship that lasted two years. Given the undeniable chemistry they shared in the film, it’s not entirely surprising that sparks flew between them in reality, too.
