Undercover lovers no more!

Though they've been dating since last spring, Emma Stone and Andrew Garfield have rarely shown affection in public. That all changed when The Amazing Spider-Man costars strolled through New York City's Chelsea neighborhood Sunday.

During their romantic stroll, Garfield, 28, was spotted making out with Stone, 23, on a street corner. The normally private pair later shopped at Parke & Ronen before eating at Tipsy Parson.

What made Stone first fall in love with The Social Network star?

"Andrew is one of the most giving actors I've ever worked with," she told Teen Vogue in September. "If I needed to get to a place of love or sadness in a scene, he'd leave messages on my phone to replay, or slip in lines off camera for a different reaction than what was scripted. He gave me so much to react to."
