The love hits just keep on coming for SANDRA BULLOCK! The Oscar winner suffered an emotional breakdown after hearing close pal RYAN REYNOLDS plans to shack up with new love BLAKE LIVELY – and even turned down a starring role in a new CLINT EASTWOOD film because of it, friends say.

“I think Sandy has been reeling over the news that Ryan is moving on with Blake,” an insider divulged.

“At one point, I’m sure she thought maybe she and Ryan had a chance at love and started looking at him as potential husband material.”

The “Blind Side” star went through a bitter 2010 divorce from badboy biker JESSE JAMES after it was revealed that he was a serial cheater during their five-year marriage. She adopted her son Louis, who is almost 2 years old, and created a beautiful new life as a mom.

“Sandra loved married life and never dreamed she’d be divorced. But after she learned of Jesse’s cheating, she knew she had to leave because she deserves better.

“As she was healing from the pain of her divorce, Ryan was right there for her and little Louis,” the source continued.

“They’d spend hours on the phone, share quiet dinners at home and go off weekends camping or enjoy movie marathons with Louis.

“Ryan makes her laugh, and before long, Sandra was laughing her tears away."
